Question

Find the range and mean of the following data:
123, 145, 122, 135, 136, 141, 156, 151, 149, 139, 120, 140, 131, 148, 129

Answer 1

Step-by-step explanation:

range=maximum value-minimum value

mean=average of all number/number of values

= 123+145+122+135+136+141+156+151+149+139+120+140+131+148+129/15

=137.6

range=156-120=36

Answer 2

hey mate!

sorted data (ascending order) = 120, 122, 123, 129, 131, 135, 136, 139, 140, 141, 145, 148, 149, 151, 156

range = highest value - lowest value = 156 - 120 = 36

median = n+1/2 = 15+1/2

so, 16/2 = 8th term = 139

hope this helps you

pls mark it as brain list
