- Histograms and box plots are valuable for assessing the impact of improvement initiatives by analyzing data before and after the intervention. Both tools can aid in identifying whether the variability remains within specification limits, whether the process is capable, and whether there are potential shifts in the process over time.

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.
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.
For data sets that impact customers, consumers, or clients, histograms can be used to measure satisfaction. Some customers may feel their needs aren’t being met and might score the process with a low number, while others score it with a high number. A histogram can help you find the average and determine if the process itself needs improvement.
1 day ago · Comparing box plots and histograms. Both box plots and histograms show the shape of your data. Both can be used to identify unusual points or outliers. Figure 3 shows an outlier box plot and a histogram for the same set of data. In this example, the histogram is vertical instead of horizontal.

Display data graphically and interpret graphs: stemplots, histograms, and box plots. Recognize, describe, and calculate the measures of location of data: quartiles and percentiles. 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 ...
