What is the mean, mode, and median of 3,8,10,12,12,14,15,15,15?

Answer 1

The first thing that you should always do when you are asked to answer a question about mean, median, or mode is to make sure that the list of numbers given are in order from smallest to largest. In your question the numbers are listed in order for you. So, go ahead & answer the question.

3, 8, 10, 12, 12, 14, 15, 15, 15

Mean: which is the average: Add the list of numbers together & divide by the # of numbers in the list.

(3 + 8 + 10 + 12 + 12 + 14 + 15 + 15 + 15) ÷ 9

104 ÷ 9 = 11.55555 or

11.6

Median: the number that is exactly in the middle of your list of numbers. For your list of numbers, that number is 12. 3, 8, 10, 12, 12, 14, 15, 15, 15

Mode: the number that occurs most frequently in your list. For your list of numbers that is 15. It is listed 3 times. 12 is listed 2 times, and the rest are only listed 1 time. 3, 8, 10, 12, 12, 14, 15, 15, 15

Answer 2

To find the mean add all the numbers together and divide by the number of values

The median would be the middle value of 9 values when placed in ascending order (the 5th value)

The mode would be the oft most occurring value that occurs more than one time
