Question 4 In the formula ¯x=a+h(∑fiui∑fi), for finding the mean

1.	Question 4 In the formula ¯x=a+h(∑fiui∑fi), for finding the mean of grouped frequency distribution ui is equal to (a) xi+ah (b) xi+a (c) xi+ah (a) a−xih
Answer» Question 4 In the formula $¯ x = a + h (\frac{\sum f_{i} u_{i}}{\sum f_{i}}),$ for finding the mean of grouped frequency distribution $u_{i}$ is equal to (a) $\frac{x_{i} + a}{h}$ (b) $x_{i} + a$ (c) $\frac{x_{i} + a}{h}$ (a) $\frac{a - x_{i}}{h}$
