inches

1 answer

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.
