Question

Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.
(a) Identify the population of interest and the sample in this study.
(b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.

Answer 1

Answer:

A) Population of interest = children between the ages of 5 and 15

Sample = 160 children between the ages of 5 and 15.

B) Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.

Yes, the findings can be used to establish causal relationship because the study is just an experiment.

Step-by-step explanation:

A) Population of interest = children between the ages of 5 and 15

Sample = 160 children between the ages of 5 and 15.

B) Sample size is 160 which is above 30.

Thus, we can say;

Yes, the results of the study can be generalized to the population if the sample is randomly selected and represents the entire population.

Yes, the findings can be used to establish causal relationship because the study is just an experiment.
