Question

A scientist measures the width of ten different tree branches in inches. The results were 18, 24, 27, 30, 21, 18, 24, 30, 30, and 24. What is the mode of the results? Question 1 options: 18, 21, 24 and 30, 30

Answer 1

The mode is the number that occurs most frequently in the set.
Putting the numbers in order will help us find the mode.
18,18,21,24,24,24,27,30,30,30

We see that 24 and 30 have an equal number of occurrences in the data set, meaning that 24 and 30 are both modes.
