Part -1:

1- what was the modal response?
2- What strikes you about this frequency distribution
3- How many students are in the "middle"?
4- Is there anything peculiar about these students' view of "average"?
5- What each column above tell you?

Part -2:

1-Compare the mean , median, and mode. As summaries of he "center" of the dataset, what are the relative merits of these three measures?
2- If you had to summarize the answers of the 218 students, which of the three would be most appropriate?explain?

Part -3:

1- in your viewer window, compare the mean, median, and trimmed mean for the two variables. Does either of the two appear to have some outliers skewing the distribution?

Part -4:
Does it confirm your judgment about the presence or absence of outliers?

Part -5:
1- how do the two resulting box-plots compare to one another?
2- What does the graph suggest about the center and spread of the height variable for these two groups? Comment on what you see.

Part -6:

1-How do the two boxplots for weight compare?
2-How do the weight and height boxplots compare to one another
3-Can you account for the differences?

Part -7:

What do these two statistics suggest about the symmetry of the data?

Part -8:

Locate the racer with a z-score of approximately 0. What does that z-score indicate about this racer?

Look at the z-score of the top two racers. How does the difference between them compare to the difference between finishers#2 and #3? Between the last two finishers?

Statisticians think of ration variables (such minutes or zminutes) as containing more information than ordinal variables (such as Rank). How does this example illustrate that difference?
