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. If you don't know why, try doing the calculation by hand to see what is .nala . ^lase Ani. 1.**larara?enh ,tanA-«A Ao..atinnanA naa anin', Tf.hat Ana, tn, nnt n ^n 0%Explanation / Answer
Answer a)
8-point data with mean of approximately 10 and standard deviation of approximately 1
= 9, 9, 9, 9, 11, 11, 11, 11
Second 8-point data with mean of approximately 10 and standard deviation of approximately 4
3, 7, 7, 10, 10, 13, 13, 17
I spaced the data a bit more around 10 unlike in the first part in which they were very close to 10. In other words, I increased the variation of data around the mean.
Answer b)
Standard deviation means the average distance of a data set from their mean or average.
Since the data set are all 50, they will have a mean of 50. Since this distance or difference between the mean (50) and each of the data point is zero (they are also 50), this implies the standard deviation is zero
