Question

Find the mean of following data

Answer 1

mean = sum of all the observations divided by the total number of observations mean = (50 + 10 + 30 + 70 + 90 )/5
= 250/5 = 50

Answer 2

Step-by-step explanation:

Mean = $\frac{Sum~of~observations}{Total~no.~of~observations}$

• $\frac{10~+~30~+~50~+~70~+~90}{5}$

• $\frac{ 250 }{ 5 }$

Mean = 50 ☑️
