Study Design – This is an overview section that includes information from your previous assignments. You should repeat the research question and hypotheses from your literature review assignment here, then briefly tell what type of study you would do, what type of data you would collect, and summarize how you would collect and analyze the data. Most of these points are covered in more detail in later sections. Population and Sample – This is a short section describing the population for your report, your sample, and how your sample will be selected. Variables and Measures – Describe the variables in your study. Indicate whether they are independent, dependent, moderating, or intervening. Describe the relationship between the variables. Tell how they will be measured. Data Collection Methods – Tell what kind of data you need to collect and how, where, and when you will collect the data. If you plan to use a survey or questionnaire, include a copy of that instrument in an appendix to your report. Also, include a copy of your cover letter for your survey. If you plan to interview, tell if it would be structured or unstructured and why. If it is a structured interview, include the questions you would ask in an appendix to the report. Data Analysis Methods – Describe the techniques you will use to analyze the data. Indicate why you selected those methods and why they are appropriate. You must be specific and detailed in identifying and justifying the processes and statistical tests you will use in the analysis of your data. References - Your report must contain a reference section that includes all sources in your paper. References must be in APA format.

Paper For Above instruction

The purpose of this report is to outline a comprehensive research plan, integrating prior assignments and providing detailed methodology for a proposed study. This includes defining the research question and hypotheses, selecting an appropriate study design, identifying the population and sample, specifying variables and measures, detailing data collection methods, and explaining data analysis techniques. This structured approach ensures clarity and rigor in the research process.

Study Design

The research question guiding this study is: "Does participation in a structured physical activity program improve mental health among college students?" The hypothesis posits that engagement in regular physical activity will lead to measurable improvements in mental health indicators such as reduced anxiety and depression levels. Given the nature of the research, a quantitative, longitudinal study design is appropriate to observe changes over time. The study will involve collecting numerical data through validated questionnaires administered at multiple time points—baseline, mid-intervention, and post-intervention. Data will be analyzed using repeated measures ANOVA to assess changes within subjects over time and to evaluate the effectiveness of the intervention.

Population and Sample

The target population for this study comprises college students aged 18–24 enrolled at a public university. The sample will be selected using stratified random sampling to ensure representation across different academic disciplines and year levels. The anticipated sample size is 150 students, which provides sufficient power to detect statistically significant effects. Participants will be recruited via campus advertisements, emails, and class announcements, with inclusion criteria being current enrollment and consent to participate.

Variables and Measures

The primary independent variable is participation in the physical activity program, operationalized as frequency and duration of exercise sessions. The dependent variables include mental health outcomes, specifically scores on standardized anxiety and depression scales, such as the GAD-7 and PHQ-9. Moderating variables, such as baseline physical activity levels and pre-existing mental health conditions, will also be recorded. The relationships hypothesized are that increased physical activity correlates with improved mental health scores. These variables will be measured through validated survey instruments, and data will be scored according to established guidelines.

Data Collection Methods

Data will be collected via structured questionnaires administered electronically through a secure online platform at three points: before the intervention, halfway through, and after the program concludes. The questionnaire will include demographic questions, the GAD-7, and PHQ-9 scales, and items assessing physical activity frequency and duration. The survey cover letter will explain the study purpose, confidentiality, and voluntary participation, and will be included as an appendix. Should interviews be utilized, they will be structured, with standardized questions designed to explore participants’ experiences and perceptions regarding the physical activity program; these will be included in an appendix.

Data Analysis Methods

Quantitative data will be analyzed using repeated measures ANOVA to evaluate changes in mental health scores over time. Multiple regression analyses may also be conducted to assess the influence of moderating variables such as initial activity levels. These methods are appropriate because they handle longitudinal data and allow for examination of within-subject changes and interactions among variables. Effect sizes will be calculated to determine practical significance, and significance levels will be set at p
