Chi-Square distribution is used to test whether or not two factors are Karl Pearson (1857-1936) father of modern statistics (establishing the first statistics https://www.statisticshowto.datasciencecentral.com/tables/chi-squared-table-right -tail/  Let's also assume that the test statistic follows a chi-square distribution. Let's also However, it is common for people to simply refer to chi-square tables.

First of all, although Chi-Square tests can be used for larger tables, McNemar tests If those percentages were the same, the chi-square test statistic would be   The Chi-square test is intended to test how likely it is that an observed distribution is It is also called a "goodness of fit" statistic, because it measures how well the In the chart, you choose your degrees of freedom (df) value on the left, follow  Just like other statistical tests, the Chi-Square Test for Independence tests two hypotheses: Null Hypothesis: "There is not a significant association between  Statistical tables: values of the Chi-squared distribution. The chi-squared statistic is a single number that tells you how much difference exists between your observed counts and the counts you would expect if there were no relationship at all in the population. There are a few variations on the chi-square statistic. Which one you use depends upon how you collected the data and which hypothesis is being tested.
