6 inches5 inches7 inches5 inches3 inches4 inches
What was the mode of the dolls' heights?

inches

Answer 1

To find the mode of the dolls' heights, we first list the heights Nina measured:

- 6 inches
- 5 inches
- 7 inches
- 5 inches
- 3 inches
- 4 inches

Now, we count how many times each height appears:

- 3 inches: 1 time
- 4 inches: 1 time
- 5 inches: 2 times
- 6 inches: 1 time
- 7 inches: 1 time

The mode is the height that appears most frequently. Here, the height of **5 inches** appears **2 times**, more than any other height.

Thus, the mode of the dolls' heights is **5 inches**.
