The important statistics formulas are listed in the chart below:

Mean barx=∑xn x = Items given

n = Total number of items

Median If n is odd, then

M = (n+12)th term

If n is even, then

M = (n2)thterm+(n2+1)thterm2 n = Total number of items

Mode The value which occurs most frequently

Variance σ2 = ∑(x−barx)2n x = Items given

barx = Mean

n = Total number of items

Standard Deviation S=σ=∑(x−barx)2n−−−−−−−−√ x = Items given

barx = Mean

n = Total number of items
