If n (number of observations) is even then we take the

• n/2th observation

• (n + 1)/2th observation

• average of (n - 1)/2th and n/2th observation

• average of (n + 1)/2th and n/2th observation

For any data, mean and median are related as:

• mean = median

• mean > median

• mean < median

• none of these
