Question

Find the mean of the data :
$20, 17, 48, 25, 29, 18, 35, 27, 42, 30$

Open in App

Solution

Step 1 : Calculate the sum of observations .
$\Rightarrow 20 + 17 + 48 + 25 + 29 + 18 + 35 + 27 + 42 + 30 \Rightarrow 291$
Step 2 : Divide the sum by number of observations .
Number of observations $= 10$
Arithmetic Mean $\Rightarrow \frac{291}{10} \Rightarrow 29.1$
Hence , Mean $= 29.1$
