Question

Use the following list to find the average or mean, the median, and the mode.

10, 15, 5, 8, 6, 6, 6

Answer 1

Respuesta:

mean = 8

median = 6

mode = 6

Explicación paso a paso:

To find the mean we add the values then divide the result by the number of values in the data set.

so

10 + 15 + 5 + 8 + 6 + 6 + 6 = 56

divide by the number of elements "7"

mean = 56/7

mean = 8

To find the median we have to arrange the values in ascending order then

5 6 6 6 8 10 15

now find the value in the middle of the data set. in this case we have 7 elements we can do

(n+1)/2

n = 7

then

(7+1)/2 = 8/2 = 4

Find the fourth element

that is

5 6 6 6 8 10 15

The median is "6"

The mode is the value that we see most often

We can see that we have 3 "sixes"

The other values only appear once

then the mode is 6
