Find the class marks of classes 10 -25 and 35 – 55.
While calculating the mean of a given data by the assumed-mean method, the following
values were obtained.
`A=25, sum f_i d_i=110, sum f_i= 50`
Find the mean.
The median of 19 observations is 30. Two more observation are made and the values of these are 8 and 32. Find the median of the 21 observations taken together.
Hint Since 8 is less than 30 and 32 is more than 30, so the value of median (middle value) remains unchanged.
