My aswer are:maximum=35
minimum=-8
median=23
mean=18
Are my answer correct?

Answer 1

Correct answers are:

maximum = 35

minimum = - 8


Your answers for the median and mean are incorrect.

Write the numbers in order from smallest to largest.

- 8 , - 3 , - 1 , 0 , 8 , 14 , 17 , 18 , 18 , 18 , 23 , 29 , 35

The median of a finite list of numbers is the "middle" number, when those numbers are listed in order from smallest to greatest.

You have 13 numbers so the median is the seventh number because it has six numbers on the left and six numbers on the right.

In this case median is 17

The arithmetic mean (or simply mean) of a list of numbers, is the sum of all of the numbers divided by the amount of numbers.

In this case:

[ - 8 + ( - 3 ) + ( - 1 ) + 0 + 8 + 14 + 17 + 18 + 18 + 18 + 23 + 29 + 35 ] / 13 =

168 / 13 = 12.92307692

mean is 12.92307692
