Question

What is the mode of this data set? {7, 10, 12, 9, 12, 4, 13, 14}

Answer 1

5; 7; 19; 24; 10; 17; 21; 6; 22; 5; 9

Arrange: 5; 5; 6; 7; 9; 10; 17; 19; 21; 22; 24

( 5+5+6+7+9+10+17+19+21+22+24 ) / 11

Mean = 145 / 11

Mean = 13,18

Mode = 5

(5 is the only value that appears most often)

Median = 10

(10 is the middle value)

Range = 24 - 5

          =19

( Range is the difference between largest and smallest values)

Answer 2

The mode of this set of data is 12
