Extracurricular activities (ECA) are part of students' everyday life; they play important roles in students' lives. Few studies have addressed the question of how student engagements to ECA affect student's grade point average (GPA). This research was conducted to know whether the students' grade point average in King Abdulaziz University, Faisaliah campus is affected by their participation in the ECA. This study also studied the students' satisfaction on ECA. The study sample includes 239 students chosen via simple random sampling method. The study used inferential statistics to analyze this study design. To achieve the purpose of this study, a questionnaire (comprising 19 questions) was designed. The results showed that participation in ECA affects the students' GPA in a positive way. The study found that those who participated in ECA have higher GPA than those who did not; the study also found that the time spent participating in ECA did not affect the time students usually spend on studying (the result showed there wasn't any relationship between them). Furthermore, the study showed that students, based on faculty, are generally satisfied with the available extracurricular activities in the campus.

I need to critique article (Extracurricular Activities and their effect on the students grade point average: statistical study) and answer this questions.

7. What type of study is it, observational, experimental, ect for this article? Explain why.

8. What type of statistics was used in study, what are the results for this article?

9. Where the results significant, at what level significant for this article?

10. What implications do the results have in this article? What type of external validity was found in study in this article ?

Explanation / Answer

5) Internal validity of this study is to validate the questionnair and redo the analysis to check whether the obtained result is correct from onother statistician.

6)the sample was selected by simple random sample. In simple random sampling each individual in the population has en equal chance of being selected in the sample.

7) This is an obsertational study.As there was no experiment conducted on the subjects and the conducted did not manipulate which group receive the agent or exposure under study.In observational study investigator iattempts to understand cause-and-effect relationships. However, unlike experiments, the researcher is not able to control :

(1) how subjects are assigned to groups

(2) which treatments each group receives.

8) We can use Pearson's chi squared test to test the associatiob between ECA and Student's GCP.

9)Here the results were significanct as participation in ECA affects the students' GPA in a positive way.As there is no level of significant mentioned here we can assume that level of significance is 5%.

10)The implications were

a)Participation in ECA affects the students' GPA in a positive way

b)Students who participated in ECA will have higher GPA than those who do not

c)The time spent participating in ECA do not affect the time students usually spend on studying
