Course Learning Outcomes

  1. It identifies appropriate sampling methods for the research problem and evaluates the impact of sampling bias on research results.
  2. It explains the basic statistical concepts, data types, and measurement levels used in psychological counseling research.
  3. It summarizes and interprets RPD data using appropriate graphical and descriptive statistical methods.
  4. It explains the concepts of sampling variability, standard error, estimation, and confidence interval, and interprets them within the context of research findings.
  5. It explains the logic behind hypothesis testing; it evaluates p-value, confidence interval, Type I and Type II errors, and effect size together.
  6. The researcher selects, applies, and interprets the results of appropriate t-tests, ANOVA, correlation, and simple linear regression methods based on the research question and data structure.
  7. It evaluates basic statistical assumptions; identifies appropriate nonparametric alternatives when necessary; and interprets key reliability outcomes in scale data.
  8. It analyzes real psychological counseling data using appropriate statistical software and reports the findings in a critical, ethical, scientific, and professional manner.
