Corresponding value for median is 61
We have to calculate mean deviation from the median. So, first we calculate the median.
we have N = 245 ⟹ N/2 = 122.5
The cumulative frequency just greater than N/2 is 154 and the corresponding value of x is 4.
Hence, Median = 4
Value corresponding to 25 is median = 13
Mean = 9
Mean = 21.65
Median = 30
We have to calculate mean deviation from the median, So, first we calculate the median,
We have N = 50 ⟹ N/2 = 25
The cumulative frequency just greater than N/2 is 30 and the corresponding value of x is 74.
Hence, median = 74
Median = 12
