Question
1.An aerobic training program is instituted in a local high school to
improve fitness levels of a single PE class. The class contains star athletes,
students who exercise regularly and occasionally, and couch potatoes. To
evaluate the program, the aerobic capacity of students is measured before the
program begins and at its conclusion. It is decided that change in aerobic
capacity will be used as the index by which to judge the success of the program.
Do you expect that the final aerobic capacity will be related to the initial aerobic
capacity in individuals? If your answer is yes, why does this not invalidate
the requirement for independence of observations required for a valid
paired t-test? (5 points)
Explanation / Answer
An aerobic training program is instituted in a local high school to improve fitness level of a singe PE class.
The aerobic capacity of studeents is measured before the programme begins and its conclusion also it is decided that change in aerobic capacity will be used as the index by which to judge the success of the programme.
yes, We except that the final aerobic capacity will be related to the initial aerobic capacity in individuals because before training programe we record the fitness level of a single PE class ( each individuals) and after training programe we record the fitness level of a single PE class ( each individuals) this means performance of each individul of PE class before training programme may be depend on the performance of each individul of PE class after training programme therefore this is not invalidate requirement for independence of observations also paired t test used for dependence of the samples.We observe the difference between performance of each individul of PE class before training programme and performance of each individul of PE classafter training programme and use z test to examine that, Is efectiveness of training program improve fitness levels of a single PE class.
