To see how wide spread the results are. If the average (mean) grade for a certain test is 60 percent and the standard deviation is 30, then about half of the students are not studying. But if the mean is 60 and the standard deviation is 5 then the teacher is doing something wrong.
8.919280881 is the standard deviation for those numbers.
I would say in America the mean IQ is about 60 and the standard deviation is about 15, this is about true for all ages.
There is insufficient information in the question to answer it. In order to compute a mean and a standard deviation, you need at least two data points, but the question only gave one. Please restate the question.
They are: 50 52 54 56 58 and 60

A large standard deviation means that the data were spread out. It is relative whether or not you consider a standard deviation to be "large" or not, but a larger standard deviation always means that the data is more spread out than a smaller one. For example, if the mean was 60, and the standard deviation was 1, then this is a small standard deviation. The data is not spread out and a score of 74 or 43 would be highly unlikely, almost impossible. However, if the mean was 60 and the standard deviation was 20, then this would be a large standard deviation. The data is spread out more and a score of 74 or 43 wouldn't be odd or unusual at all.

even numbers between 50 and 64= 52, 54, 56, 58, 60, & 62

52, 54, 56, 58, 60, 62, 64, 66, 68, and 70 are.
It is approx 55
60% of 52= 60% * 52= 0.6 * 52= 31.2
52 and 54 are multiples of 2.
