Explanation:
the mean $\stackrel{―}{x}=\frac{\sum {x}_{i}}{n}$
So applying this formula
$\stackrel{―}{x}=\frac{12+14+16+12+13}{5}=13.4$
You can also do $\stackrel{―}{x}=12+\frac{2+4+1}{5}=12+\frac{7}{5}=12+1.4=13.4$

Mean means average in statistics
$\because$ To find the average, we add up the values in the data set and then divide it by the number of values that we added
$\therefore$ mean of 12, 14, 16, 12 ,13 = (12+14+16+12+13)/5
=13.4
