Question

What are the mean and the mode of the following set of data: 5, 12, 1, 5, 7

Answer 1

Hello There!

Mean: Average of numbers in a set of data.

STEP 1: To find the mean of these numbers, we first have to add the numbers

up and get our sum. In this case, we would add 5 + 12 + 1 + 5 + 7 = 30

STEP 2: Divide the sum by the number of digits you added. We would divide

30 "sum of the numbers" by 5 "number of digits" and we would get a quotient of 6

The mean for this set of data is 6

Mode: The number that occurs most often in a set of numbers.

Looking at our numbers, we can see that the number 5 appears twice in the set and no other numbers appear more than once. This means that our mode for our set of numbers is 5

The mode for this set of data is 5

Answer 2

Mean: so basically you add up all the numbers (5+12+1+5+7=30) and divide the sum (30) with how many numbers there are (5) so 30/5=6

mode: mode is numbers repeated, since there are two 5's it is the mode (you may also have multiple modes)
