A box plot, sometimes called a box and whisker plot, provides a snapshot of your continuous variable’s distribution. They particularly excel at comparing the distributions of groups within your dataset. A box plot displays a ton of information in a simplified format.
- Step 1: Compare The Medians of Box Plots
- Step 2: Compare The Interquartile Ranges and Whiskers of Box Plots
- Step 3: Look For Potential Outliers
Compare the respective medians of each box plot. If the median line of a box plot lies outside of the box of a comparison box plot, then there is likely to be a difference between the two groups. Source: https://blog.bioturing.com/2018/05/22/how-to-compare-box-plots/
Compare the interquartile ranges (that is, the box lengths) to examine how the data is dispersed between each sample. The longer the box, the more dispersed the data. The smaller, the less dispersed the data. Next, look at the overall spread as shown by the extreme values at the end of two whiskers. This shows the range of scores (another type of d...
When reviewing a box plot, an outlier is defined as a data point that is located outside the whiskers of the box plot.
Oct 25, 2024 · A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic.
Jul 9, 2020 · Now you can use descriptive statistics to find out the overall frequency of each activity (distribution), the averages for each activity (central tendency), and the spread of responses for each activity (variability).
