Description: An introduction to basic concepts in descriptive and inferential statistics, with emphasis upon application to psychology. Consideration given to the methods of data collection, sampling techniques, graphing of data, use of statistical software, and the statistical evaluation of data collected through experimentation. Required of psychology majors.



MCCCD Official Course Competencies
1. Organize data for entry or analysis using appropriate tools (e.g., calculator, statistical software). (I, II)
2. Explain how statistics are used within the scientific method. (I, II, III, IV)
3. Use an appropriate scale of measurement to operationalize a construct of interest. (I, II, III, IV)
4. Evaluate the data collection, statistical analyses, interpretation, and presentation of research results in a variety of contexts. (I, II, III, IV)
5. Use the appropriate statistical test based on the research design (research question, data type, and number of variables). (I, II, III, IV)
6. Assess the practical implications and ethical considerations of statistical analysis in a variety of contexts beyond the classroom. (I, II, III, IV)
7. Communicate statistical concepts and research results using both technical (American Psychological Association [APA] format) and non-technical language. (I, II, III, IV)
8. Assess accuracy of data (including consideration of missing data and outliers) using an appropriate tool (e.g., calculator, graph, statistical software). (I, II, IV)
9. Verify potential violation of assumptions of a statistical test to determine the validity and reliability of results. (I, II, IV)
10. Compute descriptive statistics (including frequency distributions, measures of central tendency, measures of variability, and z-scores) and inferential statistics (including t-tests, analysis of variance, correlation/regression, and chi-square) both by hand and using statistical software. (II, IV)
11. Interpret descriptive statistics (including frequency distributions, measures of central tendency, measures of variability, and z-scores) and inferential statistics (including t-tests, analysis of variance, correlation/regression, and chi-square) using appropriate resources (e.g., results and output). (II, IV)
12. Explain the role of probability as the cornerstone of statistics. (III)
13. Utilize effect size, confidence intervals, power, and p-values to explain the statistical and practical significance of a statistical analysis. (IV)
