PDF-The sample standard deviation is large for the first data set because

contains The value of 27 is relatively large compared to the closeness in range of the other values in the set For this question you were supposed to check out the chart from Let. Let’s start with an example. I divided the class into 2 teams, A and B. Coincidentally, the quiz average for team A is the same as team B, 81.5. So we expect a graph of their scores to be about the same, right?. Professor William Greene. Stern School of Business. IOMS Department. Department of Economics. Statistics and Data Analysis.
