1. draw a histogram from all the data. each “interval” will be a single number from 0 to 10. upload the histogram once you complete the remaining steps below.

number of head in 10 sets of 10 coins
number of head is vertical
flip sets horizontal

2. calculate the mean and standard deviation.
mean = standard deviation =

3. calculate the percent of the data that is within 1, 2, and 3 standard deviations of the mean.

within 1 standard deviation = %
within 2 standard deviations = %
within 3 standard deviations = %
4. compare your results to a normal distribution. interpret any differences.
