- To become familiar with both descriptive and inferential analyses.
- To use probability as the bridge between descriptive and inferential
- To intuitively understand each concept.
- To integrate topics by identifying commonalties.
- To understand the limitations of each analysis through consideration of
- To express general concepts in terms of the application.
- To communicate results, clearly and completely, in a manner appropriate
to nonquantitative audiences.
- To be introduced to the computer's capabilities in solving practical
problems, using the computer for analysis only after understanding how to
perform the analysis manually.
- Descriptive Statistics: pictorial and tabular methods; measures of
location, variability, and position.
- Normal Distributions: percentages and percentiles for normal populations,
and Central Limit Theorem.
- One-Sample Interval Estimation: properties and assumptions, confidence
intervals for a mean and proportion, and sample size determination.
- One-Sample Hypothesis Testing: properties and assumptions, tests on a
mean and proportion, and relationship to interval estimation.
- Two-Sample Interval Estimation: properties and assumptions, confidence
intervals for the difference between two means and proportions.
- Two-Sample Hypothesis Testing: properties and assumptions, tests on the
difference between two means and proportions and the ratio of two variances
(standard deviations), and relationship to interval estimation.
- Linear Correlation: properties and assumptions, descriptive analysis, and
- Analysis of Variance: properties and assumptions, and test for
differences among two or more means.
