by looking at it and seeing the difference
Compare the shape,center,and spread of the data in the box plots with the data for stores A and B in the two box plots in example 2.
Because you can compare the values easily, for instance, you can compare the highest and lowest value and compare this to the mean, does the highest and lowest value differ greatly from the mean? Then you know the correlation is a bit unpredictable, you can also use this to compare two box plots, putting them together you can see through the median and quartile range the best way to do something, etc.
To compare two data sets displayed in box plots, you can analyze their medians, which indicate the central tendency of each data set. Additionally, examine the interquartile ranges (IQRs) to assess the spread and variability, as a larger IQR suggests more dispersion in the data. It's also important to look for overlap between the box plots, which can indicate similarity or differences in data distributions. Finally, consider any outliers that may affect the interpretation of the data sets.
You can see which has the largest spread of data.... Where the extreme values lie... The bigger the box the wider the spread of half of the data... and vice versa
No because box and whisker plots are related to cumulative frequency curves
spatial figure
Yes, I believe they can.
Nothing. Most box and whisker plots do not have 88 on them!
you use it to compare 2 different sets of data
I believe it was John Tukey in 1997
Parallel box and whisker plots are regular box and whisker plots, but drawn "one-above-the other" on the piece of paper. To enable to do this easily, draw an x-axis which is big enough for the largest value in the data, and small enough for the smallest value in the data (in the entire collection of data). Plot each box-and-whisker diagram below each other.
never, you will never use it
