There is a set of 50 scores, the mean equals 12.38 and the SD equals 4.26. Construct a SD spread figure based on these data. Be sure to specify how many data vaules are in each intercal of the figure.

Since the mean and SD are given, then because 66% of the data would be within 1 SD of the mean and 95% of the data would be within 2 SD of the mean, then you can work out the different percentages in the data and try and plot a SD graph, which would be like a bell shape to show normal distribution. Good luck!
