The t-test is used to compare the means between two groups. To determine if they are significantly different from each other or if a treatment has an effect. When to use a t-test: 1. Use a t-test to compare the means of two groups when: The data are independent. 2. The data are approximately normally distributed. 3.

RESEARCH APPROACH POSITIVISM It is an approach that seeks causal relationships among factors, with the objective of trying to predict outcomes. Positivism is based on the premise that knowledge should be gained through observable and measurable evidences CONSTRUCTIVISM An approach that suggests people construct their own understanding of the world through direct or real-world experiences and reflect upon those experiences RESEARCH DESIGN 1. Retrospective Cohort Study - In retrospective cohort study, the researcher asks the participants to report on experiences from an earlier time in their lives 2. PROSPECTIVE COHORT STUDY - In a prospective cohort study, the cohort subjects are identified based on exposure prior to the development of a condition (e.g., disorder, disease) and the outcome is observed. 3. CROSS-SECTIONAL STUDY - A cross-sectional study involves collecting data from participants at a single point in time to understand a phenomenon or experience. 4. Longitudinal Study
