![]() Q-Q Plot – this plot displays the standardized residuals against the theoretical quantiles.We can use this plot to roughly gauge whether or not the variance between the groups is approximately equal. Residuals vs Fitted – this plot shows the relationship between the residuals and the fitted values.In particular, we are most interested in the following two plots: One way to check the assumptions of normality and equal variance is to use the function plot(), which produces four model-checking plots. Equal Variance – the variances for each group are equal or approximately equal. Normality – the dependent variable should be approximately normally distributed for each level of the predictor variable.ģ. we assigned participants to the exercise programs randomly), this assumption should be met so we don’t need to worry too much about this.Ģ. Independence – the observations in each group need to be independent of each other. In particular, a one-way ANOVA assumes:ġ. Checking the Model Assumptionsīefore we go any further, we should check to see that the assumptions of our model are met so that the our results from the model are reliable. In other words, there is a statistically significant difference between the mean weight loss that results from the three programs. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1įrom the model output we can see that the predictor variable program is statistically significant at the. We can then use the summary() function to view the output of our model: #fit the one-way ANOVA model In our example, we can use the following code to fit the one-way ANOVA model, using weight_loss as the response variable and program as our predictor variable. The general syntax to fit a one-way ANOVA model in R is as follows:Īov(response variable ~ predictor_variable, data = dataset) Next, we’ll fit the one-way ANOVA model to our data to see if these visual differences are actually statistically significant. We can also see that the standard deviation (the “length” of the boxplot) for weight loss is quite a bit higher in Program C compared to the other two programs. Just from these boxplots we can see that the the mean weight loss is highest for the participants in Program C and the mean weight loss is lowest for the participants in Program A. Main = "Weight Loss Distribution by Program", We can also create a boxplot for each of the three programs to visualize the distribution of weight loss for each program: #create boxplots ![]() The following code creates the data frame we’ll be working with: #make this example reproducible We recruit 90 people to participate in an experiment in which we randomly assign 30 people to follow either program A, program B, or program C for one month. We can conduct a one-way ANOVA to determine if there is a statistically significant difference between the resulting weight loss from the three programs. The predictor variable we’re studying is exercise program and the response variable is weight loss, measured in pounds. Suppose we want to determine if three different exercise programs impact weight loss differently. The following example illustrates how to conduct a one-way ANOVA in R. ![]() Note: If we were instead interested in how two predictor variables impact a response variable, we could conduct a two-way ANOVA. This type of test is called a one-way ANOVA because we are analyzing how one predictor variable impacts a response variable. A one-way ANOVA is used to determine whether or not there is a statistically significant difference between the means of three or more independent groups.

The major key represents any of the following happiness, light, day, laughter, etc. They are listed on every line of music, which signifies what key the composer has chosen. But today the most common reason to choose a particular key is simply that the music is easiest to sing or play in that key. Even now, there are subtle differences between the sound of a piece in one key or another, mostly because of differences in the timbre of various notes on the instruments or voices involved. So why bother with different keys at all? Before equal temperament became the standard tuning system, major keys sounded more different from each other than they do now.

Speak is now in the canon of YA and is (still) taught everywhere. The side characters in the novel are well thought-out, complex, and intriguing in their own ways, despite the novel’s focus on Melinda’s struggle. It probably takes place in the late 1990s, since the book was first published in. Speak covers heavy topics and includes indirect, but powerful, messaging.

Speak: First Marking Period by Laurie Halse Anderson After calling the police during an end-of-summer party, Melinda is an outcast at school. Laurie Halse Anderson's debut young adult novel Speak, published in 1999, follows 13-year-old Melinda Sordino through her first year of high school after a traumatic incident renders her speechless and hated by most of her classmates. Melinda Sordino begins her freshman year in high school as a social outcast. Now, she faces ridicule and shame, while also attempting to speak her truth.Īnderson’s novel is incredibly well-written, conveying emotion perfectly through precise word choice.

A 'brain stethoscope' that listens for silent seizuresĪ computer music specialist has helped Stanford neurologists develop a "brain stethoscope." By converting brain waves into sound, even non-specialists can detect a certain kind of epileptic seizure.Īccording to the university researchers, medical students and nurses-non-specialists, in other words-"can listen to the brain stethoscope and reliably detect so-called silent seizures." In such neurological conditions, patients have epileptic seizures without any of the associated physical convulsions. "Our aim is to be able to set off a tsunami alarm within a few minutes from recording the sound signals in a hydrophone station," notes the lead author of the study, Usama Kadri. ![]() That makes them easy to pick up using standard underwater hydrophones, as the Cardiff University scientists demonstrated. The AGWs may travel over 10 times faster than tsunamis and spread out in all directions. The sound waves are naturally occurring, generated in the deep ocean after tsunami trigger events, such as underwater earthquakes, the university explains. Doing so helps them know what to expect well in advance of the tsunami making landfall, which suggests the possibility of better real-time early-warning systems. Scientists at Cardiff University have developed a new method to calculate a tsunami's size and destructive force by evaluating high-speed acoustic gravity waves (AGWs). "To our best knowledge, our Robat is the first fully autonomous bat-like biologically plausible robot that moves through a novel environment while mapping it solely based on echo information-delineating the borders of objects and the free paths between them and recognizing their type," according to the scientists.Ī way to detect tsunamis earlier using underwater sound waves With only sound as its input, Robat can move autonomously and map an area in real time-identifying object borders, classifying them using an artificial neural network, and avoiding obstacles. It uses an ultrasonic speaker that produces frequency-modulated chirps at a rate similar to that of bats, as well as two ultrasonic microphones that mimic ears. Like a bat, Robat emits sound and analyzes the returning echoes. Robat can map a physical space solely based on sound, according to a study by Tel Aviv University's Itamar Eliakim and colleagues, published in PLOS Computational Biology.

This was especially true for their old CMS, which tangled core modules, open-source libraries, custom-built extensions and security patches. Like other software engineers, Sticker Mule viewed its development speed and technical debt as two sides of the same coin: tighter deadlines came with messy code. It allows Sticker Mule marketers and designers to embed high-quality photos and helpful videos - a core part of nearly every page on the brand’s site - without leaving the space. With content modeling and content types, developers can create a framework for content-heavy projects and let the creatives carry it over the finish line.Ĭontentful’s ample cloud-native storage presented a bonus for the highly visual company. ![]() This breakthrough in productivity can be attributed to how the content platform defines content structures. In introducing the content platform, previously time-consuming content rollouts are now two-minute tasks that the marketing team can handle independent of developers. As developer Andre Oliveira explains, “Even a simple request from the marketing team required us to spin up new tables, wire them to views and add a form for editing content.” In this context, marketing had to prioritize initiatives and ration promotional campaigns.Ĭontentful changed all of that. Rollouts at this time were slow and expensive. Sticker Mule created a workaround, manually creating new pages to support its growing content ecosystem. To steer visitors toward the right product, Sticker Mule churned out content for specific sticker uses, which its legacy CMS struggled to accommodate. They rarely consider the specs,” says David Traver, vice president of marketing. “Where the sticker will be placed - a laptop, surfboard, window - is how consumers weigh our products. ![]() The company’s primary goal isn’t to simply build an ecommerce store but to create a great experience for those ordering online - which means considering how they shop.

The desire to create faster, more enjoyable experiences later nudged the brand to trade its legacy CMS for a more modern option. He noticed that a direct-to-consumer online model could create faster, more enjoyable experiences for customers and manufacturers, which is how Sticker Mule came about.

They even have more biting power than a grizzly bear, which has an average biting power of 1,200 PSI.Ĭonsidering the kind of environment that the hippo lives in, it’s understandable why they’d need strong biting power. That puts hippos above most felines like tigers and lions but below most alligators and crocodiles. Their canines can grow up to 1.5 feet in length.īecause of their large teeth, hippos do use them offensively.Ĭompare this to the human ability to bite no more than 200 PSI, and you can see just how strong they are. Their incisors can grow up to 1.2 feet in length. They have a total of 36 teeth that are all sharp. Hippos, on the other hand, have very large teeth. Since they’re herbivores, they haven’t evolved in such a way that requires them to use their teeth for offense or to feed themselves.Īs such, elephants don’t use their teeth offensively. They’re herbivores, so they only use their teeth to grind up plants to eat them. One of the offensive traits that many animals have is the size of their teeth and bite power.Įlephants and hippos have very big differences when it comes to their teeth.Įlephants have very small and weak teeth. Survival in Africa for wildlife usually comes down to offensive capabilities. ![]() They move on land, but they primarily prefer to travel by water.īeing able to submerge themselves under the water for long periods allows them to travel relatively safely.Īs such, elephants travel by land while hippos travel by land and water. Hippos, on the other hand, are also aquatic in nature. Their standard type of movement is also slightly different.Įlephants are firmly land-based creatures.Īlthough they like to play in the water, they don’t use it as a means of travel. However, compared to most humans, that might still be fast enough to catch a swimmer. The average top speed for hippos in the water is only five miles per hour. That said, they’re rather slow in the water. Their smaller stature likely allows them to gain a bit more speed. They have an average top speed of 20 to 30 miles per hour.Ĭlearly, hippos are a bit faster than elephants. Hippos are faster than one might think as well. Their speed allows them to charge at predators to scare them off or even attack them. They’re often able to outrun most humans. While many think that elephants are slow because of their large sizes, this isn’t actually the case. It can help an animal stay clear of a predator or give them enough momentum to cause some serious damage.Ĭoncerning elephants and hippos, there’s a slight difference between the top speeds that they can reach.Įlephants can reach speeds anywhere from nine miles per hour to 25 miles per hour. Speed matters a lot in the African wilds. The average body length of a hippo is 10.5 feet to 16.5 feet.Īlthough hippos can be quite long, they don’t quite edge out an elephant.Īs such, when comparing the two animals in terms of size, the elephant is far larger than the hippo. The average length of an elephant is 18 feet to 21 feet. The elephant has far more height on them which allows them to tower over most animals in Africa.Ī final size comparison to consider is the length. In terms of height, the average shoulder height of an elephant is seven feet to 12 feet.įor hippos, the average shoulder height is four feet to five and a half feet.Īgain, it’s clear that even the smallest adult elephant is going to be larger than the tallest adult hippo. While there are always outliers and exceptions, in most cases, the elephant is going to weigh more than a hippo. The average weight of an elephant is 6,000 to 12,000 pounds.Īs for a hippo, the average weight is 3,000 to 4,000 pounds.Ĭlearly, even the smallest elephant is still going to weigh more than the heaviest hippo. When comparing them side by side, however, it’s obvious that the elephant is a lot bigger than the hippo. When observing them on their own, you’d think that both the elephant and the hippo were quite large. One main difference that is immediately noticeable is the size between an elephant and a hippo. Here’s what you need to know about the differences between an elephant and a hippo. Since they’re both separate species, there are quite a few differences between them. However, while they are similar in many ways, they’re also very different. They both have grey-brown bodies and are quite large. ![]() ![]() Elephants and hippos are standard animals one sees in the zoo or out in the wild in Africa. ![]() 1920x1200px Dark horror gothic love romance angels gore blood girl women cities, Romantic Horror Anime HD wallpaper.2560x1440px Dark Angel Anime Dark Angel Olivia Anime, anime girl dark angel HD wallpaper.2560x1440px 2560x1440 Fallen Angel, Anime Girl, Hoodie, Darkness, Tree, Book for iMac 27 inch, fallen angel anime HD wallpaper.1920x1080px Blonde haired female anime character, Shingeki no Bahamut, Dark, anime girl dark angel HD wallpaper.1680x1050px Angel, blue, black, cute, beauty, feather, wings, sweet, white, girl, orange, dark, purple, anime, pretty, light, green, yellow, red, lovely HD wallpaper.1024x768px dark angel olivia, granblue fantasy, anime girl,, background, 5f3249, cute angel anime girl HD wallpaper.720x1280px Dark, big wings, angel, fantasy, anime, 720x1280, girl or boy angel HD phone wallpaper.2560x1700px Angels Wings Fantasy Girls angel gothic mask dark, dark demon anime aesthetic HD wallpaper.2115x1050px Dark Angel, wings, girl, black, anime HD wallpaper.2764x3500px angel, Anime, Shingeki no Bahamut, Dark Angel Olivia / and Mobile Background HD phone wallpaper.2121x1682px Angel and Background, Dark Anime Girl HD wallpaper.3507x2480px Ootengu, dark angel, Onmyouji, video game, anime, wings HD wallpaper.1920x1200px 3000354 1920x1440 Angel, Black & White, Chain, Dark, Devil, Evil, Suigintou, anime girl evil HD wallpaper.Dark Angel, Anime Angel, Angel, Female Dark Angel HD wallpaper 1366x768px Burst Angel Angels Full for your, Mobile & Tablet.1920x1200px Anime Girl Dark Angel, Fallen Angel Anime Girl HD wallpaper.2932x2932px Anime Girl Dark Angel, Cute Anime Girl Angel HD phone wallpaper.1933x1216px Black and pink haired female anime character digital, anime girl dark angel HD wallpaper.1920x1080px anime angel, anime girl dark angel HD wallpaper. ![]() 1920x1200px Anime Dark Angel 853086, Awesome Dark Angel Anime HD wallpaper.1024x768px Yin and Yang, white, black, daisuke, suit, dn angel, yin yang, dark, purple, elegant, anime, light, red, cool, dna HD wallpaper.1680x1050px Angels, wings, black, girl, angel, dark, pink, anime, moon, fantasy, luna, manga HD wallpaper.Women Piercings Anime Dark Angels px HD wallpaper 1300x975px Angel, wings, anime, dark hair, girl, long hair HD wallpaper.1728x1080px the dark angel has come, gothic, bvb, zexon, anime HD wallpaper.1024x768px Everyone Wants to be Like Dark, dn angel, evil, krad, yin yang, dark, anime, light, transform, cool, funny, good, dna HD wallpaper.2560x1600px Dark Anime, Awesome Dark Angel Anime HD wallpaper.2560x1600px Dark Angel Anime Boy And Girl HD wallpaper.1024x768px Inspirational Dark Angel Anime, Dark Angel Anime Girl HD wallpaper.Dark anime, Anime demon boy, Anime angel HD phone wallpaper 720x1280px Dark big wings angel fantasy anime 7201280 dark bi.1920x1200px Anime Angel And Demon Couple, Crying Dark Angel Anime HD wallpaper.1024x768px Angel In The Dungeon, wings, alone, cute, girl, angel, dark, anime, dungeon, yellow ribbon HD wallpaper.2560x1600px Gothic Fairy - Dark Angel Anime Girl -, Anime Fairy Girl HD wallpaper.1024x768px Dark Angel, nobusnow, Red Eyes, Anime, Original, Angel, Black Hair, Cute, Girl, Dark, Long Hair HD wallpaper.2000x1333px Dark angel olivia, Granblue Fantasy, anime girl HD wallpaper.2480x2080px Dark, big wings, angel, fantasy, anime HD wallpaper.1280x960px Anime Male Fallen Angel, Beautiful Dark Angel HD wallpaper.1024x768px dark angel, other, angel, anime, dark HD wallpaper.800圆00px Fallen Angel, black, anime, fallen, angel, dark HD wallpaper.1024x768px Anime Girl Dark Angel - & Background, Crying Dark Angel Anime HD wallpaper.Mocah, Female Dark Angel HD phone wallpaper 1563x3000px WLOP, anime girl, fallen angel. |
