Work Step by Step

The mean $\overline{x}$ of a set of data with $n$ values can be found using the formula: $\overline{x} = \dfrac{\sum{x}}{n}$ (sum of all the items divided by the number of values). Solve for the mean using the formula above to obtain: $\overline{x}=\dfrac{1+3+5+10+8+5+6+8}{8} = \dfrac{46}{8} =5.75$
