The mean of a collection of numbers is another name for the average. If you have n numbers then the mean is the sum of the numbers divided by n. In your case the mean is (1+3+4+5+7)/5 = 20/5 = 4.
Standard deviation is explained in a note in the Resource Room called A note on standard deviation. Try it with your data.
