For Tasks 1-8, consider the following data:

7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1, 7.0, 0.5, 3.9, 2.1, 4.1, 6.5

The computation should be carried out manually. All the steps that go into the computation should be presented and explained.

1.Using the list of 17 numbers at the top of the page, the median of this data, rounded to two decimal places, is:_____.

2.If you find the median using the original method (paper and pencil), you have to arrange the values into numeric order (True/False).______________________

3.The interquartile range for this data is (round each value to 3 decimal places):_______.

4.The formula for calculating the interquartile range is_____________ (show the formula and a citation to the source that you used).

5.Using techniques that we have studied in this course, the upper and lower cutoff points (rounded to three decimal places) for identifying outliers (in the given data sample) are: ________ and ________ (this is not a request to show any outliers--just the cutoff points that would determine what constitutes an outlier).You may round to three decimal places.

6.The summary() command shows a list of outliers, if there are any (True/False):______________________

7.The list of outlier values is:_____________ (if there are none, write "NA").

8.The standard deviation of the list of 17 numbers is (round to 3 decimal places): ______________
