Question 1
1.
These two histograms show the number of text messages sent in one week by two groups of 100 students. The first histogram summarizes data from sixth-grade students. The second histogram summarizes data from seventh-grade students.
Do the two data sets have approximately the same center?
Question 2
2.
These two histograms show the number of text messages sent in one week by two groups of 100 students. The first histogram summarizes data from sixth-grade students. The second histogram summarizes data from seventh-grade students.
Which data set has greater spread?
Question 3
3.
These two histograms show the number of text messages sent in one week by two groups of 100 students. The first histogram summarizes data from sixth-grade students. The second histogram summarizes data from seventh-grade students.
Overall, which group of students—sixth- or seventh-grade—sent more text messages?
Question 4
4.
Forty sixth-grade students ran 1 mile. Here is a histogram that summarizes their times, in minutes. The center of the distribution is approximately 10 minutes.
On the blank axes, draw a second histogram that has:
a distribution of times for a different group of 40 sixth-grade students.
a center at 10 minutes.
less variability than the distribution shown in the first histogram.
