hi i have a standard deviation of £3,000 per day. How do I square this on the calculation to get the variance?

If you want me to answer you should ask in the Ask the Tutor Forum (this forum is for students to help each other). To square 3,000, you multiply 3,000 by 3,000! (If you watch my free lectures, I go through the calculations).

the rule for the variances is (S.D)^2! that's it
