exercise alone. Two methods of collecting data have been proposed. Method I: Recruit volunteers who are willing to participate. Randomly assign each participant to exercise with a training partner or to exercise alone. Method II: Select a random sample of people from all the people who exercise at a community fitness center. Ask each person in the sample whether they use a training partner, and use the response to create the two groups. (a) For each method, the researchers will record the change in targeted exercise intensity for each person in the investigation. They will compare the mean change in intensity between those who exercise with a training partner and those who do not. (i) Describe the population of generalization if method I is used. Explain your answer. (ii) Describe the population of generalization if method II is used. Explain your answer.

Answer:

I) If method I is used, population of generalization will include all those people who may have varying exercising habits or routines. They may or may not have a regular excersing habit. In his case sample is taken from a more diverse population

II) Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.

The set or group of observation in which we intend to make a finding or generalize to is called the population.

The population of generalization of method 1 would include those great level of diversity as it randomly incorporates the different exercising routine(training alone and using a training partner) because it allocates participants to random groups without prior knowledge of their training routine.

Method 2 will offer a more specific generalization concept as the samples were distributed or allocated based on past training routine.

Therefore, Method 1 generalizes towards across a diverse population while method two would generalize to a population with a known or identified training regime.
