I have two groups with five numbers in each group. I want to compare how equal the groups are to each other. I have figured out the metric that I would like to use:
[MATH]\text{formula_without_name} = \frac{(\mu_A - \mu_B)^2}{\mu * \sigma}[/MATH],
where [MATH]\mu_A[/MATH] is the mean of the values in group A, [MATH]\mu_B[/MATH] is the mean of the values in group B, [MATH]\mu[I][/I][/MATH] is the mean of all ten values and [MATH]\sigma[/MATH] is the mean of the standard deviation in group A and the standard deviation in group B.
What I wonder is if this metric has a name. Has anyone else in history used it before me?
