PY 281 - Introduction to Statistics


Description
This course is an introduction to quantitative methods and analytical techniques utilized in behavior research, including research design, data analysis, and interpretation of statistics. Basic descriptive and inferential statistics are considered, including measures of central tendency and variability, the normal distribution, the t-test, ANOVA, correlation, regression, and chi-square. Statistic software SPSS is used to provide computational assistance.

General Education Learner Outcomes (GELO):
NA
Course Learning Outcomes:
  1. Evaluate statistically-based results reported in popular media by identifying the study design, assessing the validity of conclusion, and justifying whether claims are supported by the data.
  2. Formulate research questions suitable for statistical investigation and apply the statistical investigative process to analyze and interpret data to answer those questions.
  3. Create graphical displays and compute numerical summaries using appropriate software, then analyze and explain what information the displays reveal and what limitations they have.
  4. Define, illustrate, and explain how variability influences statistical conclusions and analyze examples demonstrating its impact on data interpretation.
  5. Explain and apply the concept of randomness to design valid studies and evaluate how randomization supports valid statistical inference.
  6. Construct, fit, and interpret statistical models – including multivariable models – to analyze relationships among variables and evaluate model fit.
  7. Conduct hypothesis tests and calculate confidence intervals for various scenarios, then interpret and justify conclusions in context. 
  8. Interpret, summarize, and draw conclusions from statistical software output, explaining how each component (e.g., p-values, confidence intervals, effect sizes) supports their interpretation.
  9. Identify, analyze, and propose appropriate responses to ethical issues related to data collection, analysis, and reporting in statistical practice.
