- Histograms are particularly useful in determining the underlying probability distribution of a dataset, while box plots are more useful when comparing between multiple datasets. They are less detailed than histograms and take up less space.

Histograms and box plots are very similar in their ability to visualize and describe numeric data. Although histograms are better in determining the underlying distribution of the data, box plots allow the comparison of multiple datasets as they are less detailed and take up less space.

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.
What is a Box Plot? 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.
- Visualize the Distribution of Values in a Dataset. Suppose a basketball coach wants to visualize the distribution of points scored by players on his team so he creates the following box plot
- Compare Two or More Distributions. Suppose a sports analyst wants to compare the distribution of points scored by basketball players on three different teams so he creates the following box plots
- Identify Outliers. Suppose a basketball coach wants to know if any of his players are outliers in terms of points scored. He decides to create the following box plot to visualize the distribution of points scored by his players
2 days ago · Box plots (also called box-and-whisker plots or box-whisker plots) give a good graphical image of the concentration of the data. They also show how far the extreme values are from most of the data. A box plot is constructed from five values: the minimum value, the first quartile, the median, the third quartile, and the maximum value.
1 day ago · The box plot helps identify the 25 th and 75 th percentiles better than the histogram, while the histogram helps you see the overall shape of your data better than the box plot. How do I create box plots?
Jan 4, 2021 · Box plots are useful because they allow us to gain a quick understanding of the distribution of values in a dataset. They’re also useful for comparing two different datasets. When comparing two or more box plots, we can answer four different questions: 1. How do the median values compare?
