Question

Here is a list of numbers that my teacher drew out of a hat from 49 possible numbers over the last 11 days: {35, 2, 39, 24, 19, 21, 39, 14, 24, 43, 8}. For this set of data, determine the:

a.) mean
b.) median
c.) mode

Answer 1

a) Mean = 24.4 to the nearest tenth.

b) Median = 24.

c) There are 2 modes 24 and 39.

Explanation

First list the numbers in ascending order:

2, 8, 14, 19, 21, 24, 24, 35, 39, 39, 43.

There are a total of 11 numbers.

a) Mean = sum of the above / 11 = 268/11

= 24.4.

b) Median = the middle number = 24,

c) Mode The numbers 24 and 39 occur twice so there are 2 modes.
