A manager of an inter-county hurling team is concerned that his team lose matches because they ‘fade away’ in the last ten minutes. He has measured GPS data showing how much ground particular players cover within a given time period; this is the data in list (a) in worksheet ‘Dataset3’. He has acquired the corresponding data from an opposing, more successful team, given in list (b). 1. Calculate the sample mean and sample standard deviation for the two sets of data. 2. Set up the frame work of an appropriate statistical test to determine whether there is a difference in the distances covered by the two groups of players. 3. Explain how having the results of the calculations above will influence the structure of your statistical test. 4. Carry out the statistical test and state your conclusions.

Question

A manager of an inter-county hurling team is concerned that his team
lose matches because they ‘fade away’ in the last ten minutes. He
has measured GPS data showing how much ground particular players
cover within a given time period; this is the data in list (a) in worksheet
‘Dataset3’. He has acquired the corresponding data from an opposing,
more successful team, given in list (b).
1. Calculate the sample mean and sample standard deviation for the
two sets of data.
2. Set up the frame work of an appropriate statistical test to determine whether there is a difference in the distances covered by the
two groups of players.
3. Explain how having the results of the calculations above will influence the structure of your statistical test.
4. Carry out the statistical test and state your conclusions.
