Prerequisites: PSY 101  or SOC 101  or ANT 101  and MAT 108

Description
This course introduces concepts of descriptive and inferential statistics used in the behavioral and social sciences. It includes: central tendency, variability and distributions; correlation, regression, chi square and other non-paramentic tests; hypothesis testing and sampling; type I error, type II error, confidence intervals and power; statistical packages and their application to hypothesis testing.

Learning Outcomes
Upon successful completion of the course, the student will:

1. Analyze statistical choices in published research.
2. Compute and interpret statistical formula.
3. Identify the uses and limits of specific statistics.
4. Choose appropriate statistics for analyzing data.
5. Analyze the type of data that is appropriate for hypothetical research studies.
6. Perform statistical analysis using software packages.
7. Describe the relationship between samples and populations.
8. Identify levels of measurement and statistics appropriate for the levels of measurement: nominal, ordinal, interval and ratio.
9. Describe the difference between descriptive and inferential statistics.
