The table given below gives the distribution of villages and their heights from the sea level in a certain region.
Compute the mean height, using the step-deviation method.
Let the assumed Mean be A = 1400
= h = x2 – x1 = 600 – 200 = 400
Thus, we prepare the table as below:
We know that,
Hence, The Mean height is 984.51.
