Question

What is the mean of the following set of data?

Set of Data: 10, 9, 13, 12, 18, 16

Mean=
Median=
Mode=

Answer 1

hello the mean and median are 10 and have no mode :)

Answer 2

For mean, you add up all of the numbers and then divide them by how many numbers you added.

10+9+13+12+18+16=78
since we used 6 numbers, we divide by 6.
this gives you 13 for mean.

For Median, you list them in the order of least to greatest and pick the middle one.

9, 10, 12, 13, 16, 18
since we have two middle ones after crossing out, you have to add 12 and 13 and then divide by 2. This gives you your mean of 12.5

For mode, mode is the most common number in the set of data. You have no number that is above or said twice so no mode.
