The new point made the standard deviation go way up, over 2.07. B. What did you do differently to create the data set with the larger standard deviation? I have to have two outliners on both ends of the outline in order to create the larger standard deviation and to keep the mean at five. 2) Explain in words why the standard deviation is zero when all of the points are the same. There is not a deviation from the sample because all of the data points are equal to each other. It does not deviate from itself. 3) Describe the relationship you see between the amount of spread and the size of the standard deviation and explain why this connection exists. Dont just calculate the standard deviationsexplain in words. The data sets have the same sum and width 250/5=50. In data set 1, the points are 25 points apart, in data set 2, the points are 10 points apart, and in data set 3, the points are 5...
