Calculate Variance of a variable from two date ranges
Hello I am fairly new to domo, and I am wondering how to calculate the variance of a variable in my data set from a specific time frame (Quarter 1 2019) and divide that by then variance from another time frame (Quarter 3 2018)?
So far I have tried this, but this did not match with the values from a calculation in Excel:
VAR_POP(CASE WHEN `deploy_date` >= '1/1/2019' and `deploy_date` <= '3/31/2019' THEN `delivered` ELSE 0 end) /
VAR_POP(CASE WHEN `deploy_date` >= '7/1/2018' and `deploy_date` <= '9/30/2018' THEN `delivered` ELSE 0 end)
and
VAR_POP((CASE
WHEN `deploy_date` >= '1/1/2019' and `deploy_date` <= '3/31/2019' THEN VAR_POP(`delivered`)
Else 0 end)) /
VAR_POP((CASE
WHEN `deploy_date` >= '7/1/2018' and `deploy_date` <= '9/30/2018' THEN VAR_POP(`delivered`)
Else 0 end))

Are you sure that you're looking for the population variance?
I also don't think that you would want to use the else 0 in your case statement because that will increase the N value.
You should try:
VAR_POP(CASE WHEN `deploy_date` >= '1/1/2019' and `deploy_date` <= '3/31/2019' THEN `delivered` end)
/
VAR_POP(CASE WHEN `deploy_date` >= '7/1/2018' and `deploy_date` <= '9/30/2018' THEN `delivered` end)1
