question 1
The two dot plots below compare the forearm lengths of two groups of schoolchildren:

Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?

Group A, because a child in the group has the least forearm length of 10 inches.
Group A, because four children have a forearm length longer than 12 inches.
Group B, because no child in the group has a forearm length longer than 12 inches.
Group B, because five children in the group have the least forearm length of 10 inches.

Question 2
The dot plots below show the age of some dance students and some yoga students:

Based on visual inspection of the dot plots, which group of students appears to have the larger average age?

The yoga students
The dance students
Both groups are similar.
Not enough information is available to draw a conclusion.

question 3
Lara wants to know if the number of words on a page in her English book is generally more than the number of words on a page in her history book. She takes a random sample of 25 pages in each book, then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.


Book Mean Median Mean absolute deviation
English 48.9 52 9.2
History 40.5 44 1.3


Lara claims that because the mean number of words on each page in the English book is greater than the mean number of words on each page in the history book, the English book has more words per page. Based on the data, is this a valid inference?

Yes, because there is a lot of variability in the English book data
Yes, because the mean is larger in the English book
No, because the mean is larger in the English book
No, because there is a lot of variability in the English book data
