How to interpret notched box plots - Cross Validated
WEBWhilst researching the characteristics of box plots I started experimenting with notches. I understand notches display the CI around the median, and that if two boxes' notches don't overlap there's ‘strong evidence’ – at a 95% confidence level – that the medians differ.
Box plot - Wikipedia
WEBNotched box plots apply a "notch" or narrowing of the box around the median. Notches are useful in offering a rough guide of the significance of the difference of medians; if the notches of two boxes do not overlap, this will provide evidence of a statistically significant difference between the medians. [12]
6.7 Adding Notches to a Box Plot - R Graphics
WEBNotches are used in box plots to help visually assess whether the medians of distributions differ. If the notches do not overlap, this is evidence that the medians are different. With this particular data set, you’ll see the following message: Notch …
A Complete Guide to Box Plots | Atlassian
WEBA box plot (aka box and whisker plot) uses boxes and lines to depict the distributions of one or more groups of numeric data. Box limits indicate the range of the central 50% of the data, with a central line marking the median value.
Understanding Boxplots | Built In
WEBJul 17, 2024 · A boxplot is a graph that gives a visual indication of how a data set’s 25th percentile, 50th percentile, 75th percentile, minimum, maximum and outlier values are spread out and compare to each other. Boxplots are drawn as a box with a line inside of it, and has extended lines attached to each of its sides (known as “whiskers”).
Box plots in Python
WEBA box plot is a statistical representation of the distribution of a variable through its quartiles. The ends of the box represent the lower and upper quartiles, while the median (second quartile) is marked by a line inside the box. For other statistical representations of numerical data, see other statistical charts.

WEBThis free online software (calculator) computes notched boxplots for every variable (=column) of the multivariate dataset. A notch is drawn in each side of the boxes. If the notches of two plots do not overlap this is strong evidence that the two medians differ (Chambers et al., 1983, p. 62).

WEBIn this tutorial, we add the notched option to the Box plots that are generated in the box plots tutorial. Notches allow to visualize a form of confidence intervals around the medians. When sample sizes are similar, notches allow to say roughly if medians are different or not. Setting up the dialog box for the notched box plots.
