Measurement, quantitative description and statistical inference as applied to psychological variables. Includes scientific research and statistics, descriptive statistics, inferential statistics, correlation and linear regression, and non-parametric tests.

Prerequisite(s): PSY 101 , and completion of MAT 097 , MAT 142 , MAT 151  or higher with a C or better.
Information: Prerequisite(s) may be waived with consent of instructor before enrolling in the class.
Gen-Ed: Meets AGEC - SBS; Meets CTE - SBS.

Course Learning Outcomes
  1. Analyze data for Descriptive Research Methods: Including select, prepare and interpret appropriate tables and graphs; Calculate and interpret measures of central tendency and variability. Determine and interpret distribution shapes.
  2. Analyze data for Inferential Research Methods: Including calculate and interpret standard scores; determine probabilities within the normal curve and sampling distributions. Apply and understand the steps and logic of hypothesis testing for the t-statistic, analysis of variance, and correlation. Determine and interpret statistical power and treatment effect.
  3. Choose the correct statistic for different research situations: Including descriptive, observational correlational, inferential and non-parametric tests. Obtain correct mathematical results and communicate arguments based upon that data.
  4. Define, calculate and analyze data using appropriate statistical software.
