Question

SINUL

Answer 1

Answer:

Mean=9.75

Median = 9.5

Mode = 8,9,10,12

Range = 6

Step-by-step explanation:

Arrange number in ascending order;

6,7,8,8,9,9,10,10,11,12,12,15

Mean = sum of terms/number of terms

=(6+7+8+8+9+9+10+10+11+12+12+15)/12

=117/12

=9.75

Median = middle number in a list; since we have two numbers we add them together and divide by 2

= (9+10)/2

= 19/2

=9.5

Mode = 8,9,10,12 (multimodal) this is when there are more than one mode

Range = highest number - lowest number

=15-9

=6
