Question:
A librarian in a large city collects data about his summer reading program. He collects data for two years, 2011 and 2012, on how many books are read each week. His ordered data sets are shown.
The librarian writes a summary about his data, as shown.
Click on each blank and select the appropriate word or phrase to complete the librarian's summary.
Possible Answer:
If you compare the means, it appears that in 2011, approximately 71 more books were read on average than in 2012. When the medians for the two years are compared, the data show that in 2011 approximately 15,229 fewer books were read than in 2012. As far as the spread of the data, both data sets have the same interquartile range.
