Question

Find arithmetic mean of following data:

$38,70,48,34,42,55,63,46,54,44$.

Answer 1

given raw data is $38,70,48,34,42,55,63,46,54,44.$

so the number of values $=10$

Sum of the values $=38+70+48+34+42+55+63+46+54+44$

$=494$

Arithmetic mean of the raw data

$=\frac{\text{sum of values}}{\text{number of values}}=\frac{494}{10}$

$=49.4$
