What Can We Conclude About Different Data Sets
Mr. Grammar has two English classes, one 7th grade and one 10th grade. Last week,
his students complained they have too much homework to do, so Mr. Grammar decided to take a survey.
He asked each student to log the total number of hours he/she studied for one week. Then, Mr. Grammar
compiled the results.
The following box-and-whisker plots summarize his data.
Comparing the Data: What to Consider
What can we conclude from these comparisons?
In general, tenth graders have more hours of homework per week than seventh graders have. For example, half of Mr. Grammar's tenth graders logged 4 to 11 hours of homework a week while 50% of seventh graders spent between 2 and 6 hours. The most hours reported by seventh graders was 11 hours; tenth graders reported spending a maximum of 15 hours.
