Resolved: Unable to see the "detailed discussion" in the exercise file without a Udemy account
I cannot see the discussion from the link provided in the exercise file because I don't have a Udemy account and the link sends me to their login page. So I was just curious about the discussion mentioned in the file
thanks for reaching out and sorry for the inconvenience. Here is the tip in question:
You can use the following formula:
The formula: =SUM(datapoint-mean)*(datapoint-mean)
and fix the cell with the mean, to compute the variance manually.
Hope this helps!
