  • How to interpret chi-square results for categorical variables?

    For a Chi-square test, a p-value that is less than or equal to your significance level indicates there is sufficient evidence to conclude that the observed distribution is not the same as the expected distribution.
    You can conclude that a relationship exists between the categorical variables.

  • What type of data is suitable for chi-square test?

    The data used in calculating a chi-square statistic must be random, raw, mutually exclusive, drawn from independent variables, and drawn from a large enough sample.
    For example, the results of tossing a fair coin meet these criteria.
    Chi-square tests are often used to test hypotheses.

  • Can chi-square test be used for categorical data?

    The Chi-Square Test of Independence can only compare categorical variables.
    It cannot make comparisons between continuous variables or between categorical and continuous variables.18 déc. 2023

The chi-square test is a statistical tool used to check if two categorical variables are related or independent. It helps us understand if the observed data differs significantly from the expected data. By comparing the two datasets, we can draw conclusions about whether the variables have a meaningful association.
