## What is McNemar change test?

The McNemar change test is a statistical test that can be used for paired nominal data. The McNemar test is applied to 2 × 2 contingency tables, with a dichotomous variable and matched pairs of subjects. The test then determines whether row and column marginal frequencies are equal.

**What is the p value for McNemar’s exact test?**

=0.070

The asymptotic test gives p=0.034, and the exact test gives p=0.070. The two p-values are considerably different, which often happens when we have a small sample size. The next example shows that this may also be the case for large sample sizes.

**What is the purpose of the SPSS McNemar test?**

SPSS McNemar Test. SPSS McNemar test is a procedure for testing if the proportions of two dichotomous variables are equal in some population. The two variables have been measured on the same cases. A marketeer wants to know whether two products are equally appealing.

### How is the McNemar’s test used in statistics?

McNemar’s test using SPSS Statistics. Introduction. The McNemar test is used to determine if there are differences on a dichotomous dependent variable between two related groups. It can be considered to be similar to the paired-samples t-test, but for a dichotomous rather than a continuous dependent variable.

### Is the McNemar test similar to the t test?

It can be considered to be similar to the paired-samples t-test, but for a dichotomous rather than a continuous dependent variable. However, unlike the paired-samples t-test, it can be conceptualized to be testing two different properties of a repeated measure dichotomous variable, as is explained below.

**How to calculate the chi square statistic in SPSS?**

SPSS uses the formula sing the formula (|B-C| – 1)2 / (B+C) to calculate the Chi-square test statistic. In this example, the Chi-square test statistic is found to be (|5-3| – 1)2 / (5+3) = 1/8 = .125 The p-value corresponds to the Chi-Square test statistic with 1 degree of freedom.
