Homework Help: Statistics

I need to find the measures of spread and center for each data set in a problem I am doing. How do I do that?

Also, is the center the mean(average)? Or the median?

In a normal distribution, the mean, median and mode have essentially the same value. All are measures of central tendency.

Range and standard deviation are measures of variability or spread.
