Question

the mode (rounded to the nearest tenth if needed) of the following data set is 30,29,40,51,39,33,24,60,40,35,58

Answer 1

The mode is the number that appears the most.
I'll set them up from least to greatest and in separate rows.
24
29
30
33
35
39
40, 40
51
58
60
The number that appeared the most is 40, so your mode is 40.

Answer 2

The mode is the number that occurs the most in the sequence of numbers, so the mode is 40 since that number is repeated the most in the sequence, 2 times.
