measures of dispersion(3)

range, variance, standard deviation

first arrange feom lowest to highest then: median = n+1 over 2 (odd) median= n over 2 + n over 2 + 1

mode:

find the most occuring number

range;

HV - LV

variance:

s^2= summation of (values - mean)^2 over number of values - 1

standard deviation:

s= square root of s, and square root of variance

tests null hypothesis whether it is rejected or accepted
