How to fill out estimation of vwithin-stratum variance

How to fill out estimation of vwithin-stratum variance

1. Calculate the sum of squares within each stratum by subtracting the mean of each stratum from the individual data points and squaring the result.
2. Divide the sum of squares within each stratum by the degrees of freedom within each stratum to get the variance within each stratum.
3. Calculate the average of the variances within each stratum to get the estimation of vwithin-stratum variance.
