Answer 1

Answer:

For grouped data, we cannot find the exact Mean, Median and Mode, we can only give estimates. To estimate the Mean use the midpoints of the class intervals: Estimated Mean = Sum of (Midpoint × Frequency)Sum of Freqency. To estimate the Median use: Estimated Median = L + (n/2) − BG × w.

Answer 2

Answer:

Mode=l+{(f1-f0)/(2f1-f0-f2)}×h

Median=l+{(n/2-cf)/f}×h
