PSY255

Introduces the student to the concepts of descriptive and inferential statistics. Research needs to be summarized by appropriate descriptive statistics such as central tendency, variability, and distributions. Relationships will be studied using correlation, regression, chi-square, and other non-parametric tests. Research also needs to be analyzed by appropriate inferential statistics such as t-tests and analysis of variance (ANOVA). Hypothesis testing, sampling, significance levels, type I errors, type II errors, confidence intervals, and power will be discussed. The student will be introduced to SPSS and/or other appropriate software for performing the descriptive and inferential statistical procedures presented in the course. The approach will be on practical considerations not theoretical issues.
