Question
Here is a set of data. 8 3 4 7 5 2 3 1Find the mean of the data.Give your answer correct to 1 decimal place where appropriate.
Solution
To find the mean (average) of the data, you need to add up all the numbers and then divide by the count of the numbers.
Here are the steps:
- Add up all the numbers: 8 + 3 + 4 + 7 + 5 + 2 + 3 + 1 = 33
- Count the numbers. There are 8 numbers in the data set.
- Divide the sum by the count: 33 ÷ 8 = 4.125
So, the mean of the data is 4.1 (correct to 1 decimal place).
