Use McNemar S Test to Compare Two Proportions from Matched $\alpha = 0.05$

question 103

Short Answer

Use McNemar s Test to Compare Two Proportions from Matched -pairs Data
-Test whether the population proportions differ at the $\alpha = 0.05$ level of significance by determining the null and alternative hypotheses, the test statistic, and the critical value. Assume that the samples are dependent and that they were obtained randomly.

Definitions:

Population Means

The average value of a set of characteristics within a total population.

Sample Means

Refers to the average values computed from multiple samples from a population, usually to estimate the population mean.

Pooled Variance

combines the variances of two or more groups, assuming they have the same underlying variance, to estimate a common variance.

Common Variance

The variance shared by two or more variables, often used in the analysis of variance.
