Question

Find the mean, median, and mode(s) of the data set.
3, 41, 11, 3, 11, 5, 11

Answer 1

Mean - 11.61

Median - 11

Mode - 11

To find the mean, add all numbers and divide by the amount of numbers there. The total is 82. Divide that by 7 and you get the mean of 11.61.

For Median, you’d have organize the numbers from smallest to largest, giving you this: 3, 3, 5, 11, 11, 11, 41. Thus, your median is 11.

Mode is the value repeated most often, thus making it 11.

Hope this helps!

Answer 2

There are 7 terms in this set.

Order the set from lowest to greatest:

3, 3, 5, 11, 11, 11, 41

To find the mean, divide the sum of the terms by the amount of terms:


`(3 + 41 + 11 + 3 + 11 + 5 + 11) / 7`

`85 / 7 = 12.14`

The mean of this set is 12.14.

To find the median, add the number of terms by 1, then divide by 2 to determine what number you'll use:


`(7 + 1) / 2`

`8 / 2 = 4`

The median will be given by the 4th number of the ordered set, which is 11.

The mode is the number that is repeated most in the set.

There are two 3's in the set, and there are three 11's in the set. 11 is the most common number in this set, so the mode is 11.
