Question 2

Analyse the heart rate data collected during a VO2 max test. The data points (observations) were collected at the point the lactate threshold occurred (the point at which blood lactate deviates from resting concentrations) before and after a six-week aerobic training programme. Interpret the SPSS output and decide whether the two data sets are normally distributed.

Accepted Answer

A)  Both pre- and post-test data sets are normally distributed. 
B)  The pre-test data set is normally distributed but the post test data set is not. 
C)  The post-test data set is normally distributed but the pre-test data set is not. 
D)  Neither data set is normally distributed. 
A)  Both pre- and post-test data sets are normally distributed. 
B)  The pre-test data set is normally distributed but the post test data set is not. 
C)  The post-test data set is normally distributed but the pre-test data set is not. 
D)  Neither data set is normally distributed.

B)  The ability of a statistical test to yield appropriate participant numbers. 
C)  The ability of a statistical test to successfully identify the confidence intervals of a sample mean. 
D)  The ability of a statistical test to apply a meaningful effect.
