Dataset, Database Management System

The dataset "CFOLYMPICS.XLS" contains the observations used in the above article.  The definitions of the variables are also included in this spreadsheet.  However, for the purposes of this exercise the data will be 'modified' as explained below, so you should not rely on any results that are given in the source text or of other students.

Take a copy of the dataset from Blackboard.  In order that each student works with a slightly different dataset the following procedure should be applied to create data in columns H and I.

(a)   From the main menu select Tools > Data Analysis > Random Number Generation and click OK.  Complete the option window as adjacent, i.e.

(b)   Select 'Bernouilli' from the Distribution drop-down list

(c)    Select a p-value equal to 0.08

(d)   Set the output range in the usual way to the values shown: but....

(e)   In the Random Seed box enter the last 4 digits of your Student Number (omitting any leading zeros i.e. 0123 becomes 123) as it will appear on the cover sheet you will submit (see end of this document).  It is important that these two values match.

(f)     Click on OK to return to the spreadsheet.

(g)   In the spreadsheet cell I2 enter the cell formula:-

=3*E2+2*F2+1*G2+1+H2

and drag it down the I column.  In this exercise we are going to work with the concept of winning 'points' awarding 3 for gold, 2 for silver, 1 for bronze and an extra 1 for having a team present.  The last component awards an extra point randomly to some of the year/country results.

The implications of this procedure are that each student will be working with a slightly different dataset.  In consequence it may prove perfectly legitimate for you to reach a conclusion about any of the following questions which differ from those reached by other students.  This should not preclude you however from discussing the method of the analyses you carry out with other students or me.  Indeed I would encourage such discussions since you will thereby get practice in using the jargon of our subject.  This exercise will use the measure of 'points' for Olympic success in comparison to 'medals' in the cited article.

For each of the following questions make a copy of the initial data as required and place on a new clean sheet.  This should be done by using 'Paste Special' and selecting the 'Values' option so that no cell formulae are compromised by the copy process.
