Course Outline
Stat 2561
Statistics For Professionals 2
Review of inferential statistics (confidence intervals and hypothesis tests for a single quantitative
variable mean and the difference between two quantitative variable means)
Inferences for a single proportion and for the difference between two proportions
(point estimation, confidence intervals, and hypotheses tests)
Categorical data analysis:
Pearson chi-square tests for a single categorical variable
Contingency table analysis (tests of independence / homogeneity for two categorical variables)
Linear regression and correlation
Simple linear regression (least squares estimation of regression coefficients, estimation of variance
parameter, confidence intervals and hypotheses tests for regression coefficients)
Correlation (calculation and interpretation of correlation coefficient, including caveats)
Multiple regression (can include a brief discussion or overview if time is limited)
Analysis of Variance
Single-factor ANOVA (point estimation of group means and variance parameter, hypothesis test of
equality of group means, multiple comparisons)
Two-factor ANOVA (hypothesis test for a treatment effect in a completely randomized design and/or
a randomized block design)
Analysis of covariance (can include a brief discussion or overview if time is limited)
Study design
Experimental vs. observational designs
Completely randomized vs. randomized block experimental designs
Matched vs. unmatched data
1. In general, emphasis should be on “statistical reasoning” as opposed to “statistical calculations”.
2. The TI-83 or 84 calculator is required for this course. Please do not use built-in STAT functions to
compute confidence intervals or perform hypothesis tests until after the students have mastered
these concepts.
3. Students should receive some exposure to statistical software output (such as Minitab or SPSS).
Outline of topics from “Statistics: Principles and Methods” (6e) by Johnson and Bhattacharyya:
11. Regression Analysis − I (Simple Linear Regression)  Can deemphasize Section 6.4
12. Regression Analysis − II (Multiple Linear Regression and Other Topics)  Can cover this
material briefly in any way one desires
13. Analysis of Categorical Data
14. Analysis of Variance (ANOVA)
