Question

Study the stem plot and histogram. Write a few sentences to describe the distribution of amounts these customers spent. Be sure to address the characteristics of shape, center, spread, and any unusual features using only these graphs. (Do not look ahead for any calculations.) Your sentences should be complete and grammatically correct. Based on your first look at the graphs, do you expect the median is significantly less than the mean, significantly more than the mean, or approximately the same as the mean? Justify your choice.

Explanation / Answer

c. Although you see a 'normal' type distribution, clearly we see a skew in distribution.

The distribution of book cost is skewed right clearly.

You can see a lot of data points with high book cost at $600,$700 and $800.

The mode is at $300 clearly, that' the highest frequency

Mean > Median as there is right skew.

Now, since we have right skew, median will be most probably higher than mode between $300 and $500

d. Median and mean shouldn't be significantly diffeernt in this case as the distribution is not so skewed, ie. we have very less frequency as outliers ( unusuals)
