Psychological Statistics

This course covers how quantitative methods are used to answer questions in psychology. Students examine psychological applications of measures of central tendency, measures of variability, frequency distributions and standardization of scores (z-scores). Students learn to conduct, interpret, and report effect sizes and significance testing for comparing means (z-tests, t-tests and ANOVAs with one and two factors), and for assessing relationships (bivariate correlation and regression) within research scenarios commonly encountered in psychology. Special attention is given to identifying the appropriate statistics to use for a given research question and data set, to ethical issues in data analysis, and to the use of statistical software.
