Mean

x̄ = (Σ(i=1 to n) x_i)/n = (x_1 + x_2 + ... + x_n)/n

x̄ = (Σ(i=1 to n) f_i x_i)/(Σ(i=1 to n) f_i) = (Σ f_i x_i)/N

d_i = x_i - a

x̄ = a + (Σ f_i d_i)/N

x_i = (lower class limit + upper class limit)/2

Median

Median = ((n+1)/2)th observation

Median = [ (n/2)th observation + (n/2 + 1)th observation ] / 2
