Question

▶

The students in Hugh Logan's math class took the Scholastic Aptitude Test. Their math scores are shown below. Find
the mean score.
534 636 352 355 570
359 354 539 470 482
A. 456.0
B. 476.0
C 465.1
D. 474.6

Answer 1

C) 465.1

Explanation:

The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is

`\mu = \frac{{\sum}x}{N}`

The formula for the mean of a sample is

`\bar{x} = \frac{{\sum}x}{n}`

Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:

`(4651)/(10) = 465.1`

Answer 2

The answer is C, you have to add all the numbers up first. When you add you get 4561. To get the average you take that number and divide it by 10 since that’s how many scores there are. Hope that makes sense :)
