A group of student athletes was training for an obstacle course event by practicing a variety of exercises. Their coach wanted to know if the exercises were in fact related to their time to complete the obstacle course. Time 1 was each athlete's time (in seconds) for 20 repetitions of shuttle runs (running back and forth between 2 cones placed 25 meters apart) during training. Time 2 was the same athlete's time (in seconds) to complete the obstacle course during the competition. If the coach wants to see if there was an association between time to complete 20 shuttle runs during training (in seconds) and the time to complete the obstacle course during competition (in seconds), which of the following is the appropriate inference method to analyze these data? Two independent samples Inference for regression Matched pairs

Jaylah Leblanc · Answer 1

Matched pairs

Step-by-step explanation:

Here each athelete's time to complte 20 shuttle runs is to be compared with his/her time to complete the obstacle course is to be compared to determine their association

Inference for regression will be sutiable if their association is already known or if they can be realted via mathematical model.

Independent samples method can't be used as outcome of one experiment is to be matched with outcome of other experiment
