HMEF5113: Describe how you would go about addressing missing values in a dataset when respondents failed to fill up their responses: Statistics for Educational Research Assignment, OUM, Malaysia

HMEF5113 Dataset for Assignments 1 and 2 May 2023. Sav was extracted from an experimental research study that was undertaken to determine the impact of two different types of interventions in helping students cope with their anxiety concerning a forthcoming statistics course. Students were divided into two equal groups and asked to complete several scales (Time 1).

These included a Fear of Statistics test, a Confidence in Coping with Statistics scale, and a Depression scale. One group (Group 1) was given several sessions designed to improve mathematical skills, and the second group (Group 2) was subjected to a program designed to build confidence in the ability to cope with statistics. After the program (Time 2) they were again asked to complete the same scales that they completed before the program. They were also followed up three months later (Time 3). Their performance on a statistics exam was also measured.

1. Describe how you would go about addressing missing values in a dataset when respondents failed to fill up their responses.
2. Generate a frequency count and bar to show the distribution of gender classification. Describe the frequency distribution output.
3. Was the intervention effective in increasing students’ confidence in their ability to cope with statistics? You will need to use the variables, confidence time1 (conf1) and confidence time2 (conf2). Write your results in a report.
4. What impact did the intervention have on students’ levels of depression?
5. Use one-way repeated measures ANOVA to compare the Fear of Statistics scores for the three-time periods (time1, time2, and time3). Inspect the means plots and describe the impact of the intervention and the subsequent follow-up three months later.
6. Is there a significant interaction effect between the type of intervention (group) and time?
7. Is there a significant main effect for the within-subjects independent variable, time?
8. Is there a significant main effect for the between-subjects independent variable, group (maths skills/confidence building)?
