Data analysis made easy. For biologists, especially.
A box and whisker plot, or just box plot, is a graph that visualizes how spread-out a dataset is. A box plot displays 5 values: minimum, first quartile, median, third quartile, and maximum. How to read a box plot: The box is drawn from the first quartile to the third […]
“How to extract the biology behind this huge matrix of thousands of rows and columns?” Large numbers of data points hold valuable biological stories yet are tricky to graph and analyze. Imagine you had the data for 1000 features and observations, your mind would be full of questions, wondering how […]
We showed a quick and easy way to compare box plots in previous post. Let’s dig deeper into what information you can use to compare two box plots. Overlapping boxes and medians It gets tricky when the boxes overlap and their median lines are inside the overlap range. As always, math comes to […]
Box plots, a.k.a. box-and-whiskers plots, are an excellent way to visualize differences among groups. They manage to carry a lot of statistical details — medians, ranges, outliers — without looking intimidating. But box plots are not always intuitive to read. How do you compare two box plots? The key information […]
Box plots, a.k.a box-and-whisker plots, are an excellent way to compare groups. They are intuitive: viewers can see samples’ medians, distribution, and variabilities with a quick glance. They allow comparing samples of different sizes; for example, a set of 50 data points with a set of 30. They don’t even […]
Writing a scientific paper? Preparing for publication? Making a poster for a conference tomorrow? Let’s face it: People will skim through the body text of your paper/poster, and only look at the figures. We all love figures. They catch eyes, they deliver information effectively, they highlight your results. Figures are […]
