Using n=20 dots, move dots on the dot plot so that the mean is 5 and the standard deviation is more than 6. Explain how you changed the data. Why did that have the desired effect on the measures of center and spread? Using n=20 dots, move dots on the dot plot so that the mean is less than 3 and the standard deviation is less than 1. Explain how you changed the data. Why did that have the desired effect on the measures of center and spread? Is it possible to create a data set with a mean of 0 and a standard deviation of 0? Why or why not
