Inferential Statistics –
mth464
(3 credits)
This course presents techniques for analyzing data and uses of inferential statistics. Students examine the applications of hypothesis testing using normal probability distribution, t-distribution, analysis of variance (ANOVA), linear regression, and nonparametric data.
This undergraduate-level course is 5
weeks.
To enroll, speak with an Enrollment Advisor.
-
Inferential Methods in Regression
Verify that residuals are normally distributed.
- Formulate a hypothesis test to determine if an independent variable is useful for making decisions.
- Construct prediction intervals for individual responses.
- Construct confidence intervals for mean responses.
- Determine if a linear relationship exists between a dependent and independent variables.
-
Analysis of Variance (ANOVA)
Interpret the summary output of ANOVA tables.
- Perform two-way ANOVA designs.
- Perform hypothesis tests using one-way ANOVA.
Perform tests of hypothesis to determine whether the variances of two populations are equal.
-
Hypothesis Testing
