# Find the variance of $$2, 6, 8, 6, 2,$$ and $$6.$$

### Question

Find the variance of $$2, 6, 8, 6, 2,$$ and $$6.$$

### Options

A) $$6$$

B) $$5$$

C) $$\sqrt{6}$$

D) $$\sqrt{5}$$

### Explanation:

The mean $$\bar{x} = \frac{\sum x}{n}$$ $$= \frac{30}{6} = 5$$

Variance $$= \frac{\sum (x - \bar{x})^2}{n}$$ $$= \frac{30}{6} = 5$$

## Discussion (4)

• Okewole Oluwabori

Variance=4

• The mean $$\bar{x} = \frac{\sum x}{n}$$ $$= \frac{30}{6} = 5$$
Variance $$= \frac{\sum (x - \bar{x})^2}{n}$$ $$= \frac{30}{6} = 5$$
