Chi Square Test Yes No Data

Similarly each column shows the categories of another variable. But large p-values dont.

CHISQTESTactual_rangeexpected_range The CHISQTEST function syntax has the following arguments.

. In other words the assumption of normality is not required to perform the test. Each variable must have two. You can use χ2 tests to determine whether hypothesized results are verified by an experiment.

Figure 1 Data and Chi-square test for Example 1. This test is usually run using technology. Chi square test utilizes a contingency table to analyze the data.

Like most goodness of fit tests these small p-values usually under 5 mean that your model is not a good fit. As you can see from Figure 1 the expectation for two of the cells G6 and H6 is less than 5. Since Excel 2003 is no longer supported by Microsoft I have not made further bug fixes to this release.

Each row shows the categories of one variable. CHISQTEST returns the value from the chi-squared χ2 distribution for the statistic and the appropriate degrees of freedom. Small p-values mean that the model is a poor fit.

The output returns a chi-square value a Hosmer-Lemeshow chi-squared and a p-value eg. Chi square test of independence is a non-parametric test. Yes there was a bug in the calculation of this value that was fixed a long time ago.
