Computer Color is Broken

Wheezy Waiter announces the SciShow nominees for "Worst Science in a Film," & Hank talks about the bird flu and shares two sounds that had never been heard by human ears until very recently.

There are about 450 million diabetics around the world, and while we do already have a reliable way of measuring blood sugar, it requires patients to prick their finger each time they want a reading. Is there a better way?

Should we keep the outdoors out of hospitals? Ecologist and TED Fellow Jessica Green has found that mechanical ventilation does get rid of many types of microbes, but the wrong kinds: the ones left in the hospital are much more likely to...

Hank breaks the news to you about your brain on football, the reality behind the latest moon-base plan, and an epic win -- and fail -- in the animal kingdom.

Today we’re going to talk about how neurons in a neural network learn by getting their math adjusted, called backpropagation, and how we can optimize networks by finding the best combinations of weights to minimize error. Then we’ll send...

Data mining recently made big news with the Cambridge Analytica scandal, but it is not just for ads and politics. It can help doctors spot fatal infections and it can even predict massacres in the Congo.

Does collecting more data lead to better decision-making? Competitive, data-savvy companies like Amazon, Google and Netflix have learned that data analysis alone doesn't always produce optimum results. In this talk, data scientist...

What if we could grow delicious, nutrient-dense food, indoors anywhere in the world? Caleb Harper, director of the Open Agriculture Initiative at the MIT Media Lab, wants to change the food system by connecting growers with technology....

We've talked a lot about modeling data and making inferences about it, but today we're going to look towards the future at how machine learning is being used to build models to predict future outcomes. We'll discuss three popular types...

Trust: How do you earn it? Banks use credit scores to determine if you're trustworthy, but there are about 2.5 billion people around the world who don't have one to begin with -- and who can't get a loan to start a business, buy a home...

Today we're going to discuss how machine learning can be used to group and label information even if those labels don't exist. We'll explore two types of clustering used in Unsupervised Machine Learning: k-means and Hierarchical...

Why do so many companies make bad decisions, even with access to unprecedented amounts of data? With stories from Nokia to Netflix to the oracles of ancient Greece, Tricia Wang demystifies big data and identifies its pitfalls, suggesting...

Amy Webb was having no luck with online dating. The dates she liked didn't write her back, and her own profile attracted crickets (and worse). So, as any fan of data would do: she started making a spreadsheet. Hear the story of how she...

Today we're going to introduce one of the most flexible statistical tools - the General Linear Model (or GLM). GLMs allow us to create many different models to help describe the world - you see them a lot in science, economics, and...

In this video Paul Andersen explains how to run the student's t-test on a set of data. He starts by explaining conceptually how a t-value can be used to determine the statistical difference between two samples. He then shows you how to...

Today, we're looking at measures of spread, or dispersion, which we use to understand how well medians and means represent the data, and how reliable our conclusions are. They can help understand test scores, income inequality, spot...

Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are...

In this video Paul Andersen explains the importance of standard deviation. He starts with a discussion of normal distribution and how the standard deviation measures the average distance from the mean, or the "spread" of data. He then...

Today we’re going to finish up our unit on data visualization by taking a closer look at how dot plots, box plots, and stem and leaf plots represent data. We’ll also talk about the rules we can use to identify outliers and apply our new...

In the short math video we will learn how to find the median of a set of data displayed in a dot plot.

In this video, we will look at the impact of the data changes we make with underlying data in the measures of central tendency or dispersion.

In this video, let's learn to calculate the F ratio for the two-way ANOVA, interpret the results, and draw conclusions.
