To calculate the difference between two dates in different columns, we use the two columns createdDate and LastLogin of the registration table and apply the DATEDIFF function on these columns. To find the difference between the two dates in different columns, we need two dates from the different columns.

Effect size equations. To calculate the standardized mean difference between two groups, subtract the mean of one group from the other (M1 – M2) and divide the result by the standard deviation (SD) of the population from which the groups were sampled.
