Course Outline

STAT 142

Title:  Introduction to Statistics

 

 

Introduction to Statistics

Descriptive statistics (including graphical methods)                      

Concepts of probability (including binomial and normal distributions)                   

Sampling distributions 

 

Point estimation, confidence intervals, and hypotheses tests:

      for a single mean

      for the difference between two means  (independent and paired samples)

      for a single proportion (using normal approximation)

      for the difference in two proportions (using normal approximation; optional)

 

Study design

      Experimental vs. observational designs

      Completely randomized vs. randomized block experimental designs

      Matched vs. unmatched data

 

Simple linear regression and correlation  (optional)

      Least squares estimation

      Inferences for regression parameters

      Correlation

     

 

 

 

Remarks

 

1.      In general, emphasis should be on “statistical reasoning” as opposed to “statistical calculations”.

 

2.      The TI-83 calculator is required for this course.  Please do not use built-in TI-83 STAT functions to compute confidence intervals or perform hypothesis tests until after the students have mastered these concepts.
