The chi-square test is a hypothesis test used for categorical variables with nominal or ordinal measurement scale. The chi-square test checks whether the frequencies occurring in the sample differ significantly from the frequencies one would expect. Thus, the observed frequencies are compared with the expected frequencies in the Chi2-Test and ...

In this video, we demonstrate how to calculate the expected values for a two-way contingency table under the assumption that the two categories are independent of each other. We are learning how to find these expectations in preparation of performing a chi-square test of independence. My website https://www.statsprofessor.com/ organizes all of ...

A chi-squared test (also chi-square or χ2 test) is a statistical hypothesis test used in the analysis of contingency tables when the sample sizes are large. In simpler terms, this test is primarily used to examine whether two categorical variables (two dimensions of the contingency table) are independent in influencing the test statistic ...

One of the statistical tests used in A Level Biology, the Chi-squared test is used to compare observed results with expected results. Expected results from tests can be evenly distributed or can be expected to fit certain phenotypic ratios. This video will teach you how to use the Chi-squared with and without phenotypic ratios. - why you need ...
