Question

led to the s points) B. Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1. Use the second chart to create a second data set with 8 points that has a mean of approximately 10 and a standard deviation of approximately 4. What did you do differently to create the data set with the larger standard deviation? (4 points) 2. Go back to the spreadsheet and clear the data values from Question 1 from the data column and then put values matching the following data set into the data column for the first graph. (S points) 50, 50, 50, 50, 50 Notice that the standard deviation is 0. Explain why the standard deviation for this one is zero. Do not show the calculation. Explain in words why the standard deviation is zero when all of the points are the same.

Explanation / Answer

B) Create data set with 8 point in it that has mean of approximatly 10 and SD approximately 1 is
Data 1

Mean = 10 , SD = 1.224744871

Create data set with 8 point in it that has mean of approximatly 10 and SD approximately 4 is
Data 2

15.5
Mean = 10 , SD = 4.038873605

To create large standard deviation, we consider the large gap between the values

2) Since all values are equal to 50, the standard deviation of the data set is zero.

The difference between the values is decrease the SD decreases and vice-versa.
Here the difference between the values is zero the SD is zero
