Question

what is the mean?
1 4 2 1 7 3 3 0 5 4

Explanation:

Step1: Calculate the sum of the data

$$1 + 4+2 + 1+7 + 3+3 + 0+5 + 4=30$$

Step2: Count the number of data points

There are \(n = 10\) data points.

Step3: Calculate the mean

The formula for the mean \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). Substitute the sum (\(\sum_{i=1}^{n}x_{i}=30\)) and \(n = 10\) into the formula: \(\bar{x}=\frac{30}{10}=3\)

Answer:

\(3\)
