Question

The marks scored by $11$ students in Mathematics test are as follows:
$34, 37, 30, 38, 50, 34, 34, 38, 36, 45, 31$ . Find the mean

Open in App

Solution

We know that,
$M e a n = \frac{t o t a l n o . s u m}{t o t a l s t u d e n t s}$
$\begin{matrix} = \frac{30 + 31 + 34 + 34 + 34 + 36 + 37 + 38 + 38 + 45 + 50}{11} = \frac{407}{11} = 37 \end{matrix}$
