variance of discrete uniform distribution
...ete uniform distribution on [1,12]
the mean is (1+12)/2=6.5
which is ok.
y=1:12
mean(y)
then var(y)
gives me 13
1- on http://en.wikipedia.org/wiki/Uniform_distribution_%28discrete%29 wiki
the variance is (12^2-1)/12=143/12
2-
http://www.solvemymath.com/online_math_calculator/statistics/continuous_distributions/uniform/param_uniform.php
here
which used (12-1)^2/12=121/12
all different 3 answers!!!
All I am looking for is the variance of a random variable from discrete
uniform distribution.
Can someone clearify that for me please?
Thanks.
