Question

find the mean of 10, 4, 2, 8 graphically.
10 + 4 + 2 + 8 = 24
what is the average value?

Explanation:

Step1: Calculate the sum of the numbers

$$10 + 4+2 + 8=24$$

Step2: Determine the number of values

There are \(n = 4\) values (\(10\), \(4\), \(2\), \(8\)).

Step3: Use the mean formula

The mean formula is \(\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}\). Substitute \(\sum_{i=1}^{n}x_{i}=24\) and \(n = 4\) into the formula: \(\bar{x}=\frac{24}{4}\)

Answer:
