Hello All:
I'm afraid that I'm not sure what to do here. I am given the following information:
Sample size: 5
Mean: 3.0
Sum of squared values: 65
I am asked to compute the standard deviation, given these data. Could someone please suggest a formula with a step-by-step solution?
Thank you for your time,
Panglot
Thank you, pickslides,
My only difficulty here is that I cannot seem to get an answer of 2.24 when I attempt to solve this problem using the standard equation. If possible, could you walk me through this particular problem so that I will know exactly what goes where?
Thank you,
Panglot
Multiply my answer 2 by root(5/4) to get the required answer.
What's happening is that if they ask for the sample SD the answer is 2 but if they want an estimate of the population SD you multiply the sample SD by root(n/n-1) which in your case is root(5/4)
