The whiskers are absent. One way to help you interpret box plots is to imagine that the way a data set looks as a histogram is something like a mountain viewed from ground level and a box-and-whisker diagram is something like a contour map of that mountain as viewed from above.

The
five-number summary of the data set. The value of the mean isn’t included on a box plot. The length of the box becomes its height. There are no obvious outliers in any of the samples. The interpretation of the compactness or spread of the data also applies to each of the 4 sections of the box plot. the length of the box. A box and whisker plot is a visual tool that is used to graphically display the median, lower and upper quartiles, and lower and upper extremes of a set of data.. The top whisker

The length of the box is thus the interquartile range of the sample. Box plots are useful as they provide a visual summary of the data enabling researchers to quickly identify mean values, the dispersion of the data set, and signs of skewness. Each step is color coded to match a part of the picture provided. INTERPRETING Box and Whisker Plots-A box and whisker plot separates data into FOUR sections…The two parts of the box and two whiskers.
