Project #32961 - Statistics

 

Math 1107

Need help with quiz and activity assignment due Sunday, June 15th. Listed below is sample quizz and activity due.

The table on page 1 has four histograms and boxplots of four datasets. I erased the labels on the

x-axis on the histograms and the labels on the y-axis on the boxplots on purpose. You have to do your best in matching the histograms to their respective boxplots based on their appearance and special features.

I did not put labels on the plots in the table, but call the histograms in the first column H1-H4 and the boxplots in the second column B1 - B4.

You will work in groups on this activity. Talk about the graphs and post your answer as a group by giving reasons why you matched the plots the way you did. Look for pointers such as: shape (symmetric or skewed, what indicates skewness and in which direction), position of median, spread (range or IQR, how does it indicate concentration around the center of the distribution), outliers.

There is a second file as part of this activity in which the labels are shown, making the matching easier. I would like you to look at the second file AFTER you decide on the answer by matching the plots by using this file only. If you decide you want to make changes after you look at the second file please add those changes to your post.

Keep in mind, I am not that much interested in you matching them perfectly (honestly, I don’t know if I can match them now). It is far more important to see how you are using the information you can get right now in matching them.
