An X2 analysis, commonly known as chi-squared analysis, is a statistical method used to determine if there is a significant association between categorical variables. It compares the observed frequencies of occurrences in a dataset to the expected frequencies under the assumption of independence. The chi-squared statistic is calculated, and its value is compared against a critical value from the chi-squared distribution to assess whether to reject the null hypothesis. This analysis is widely used in fields such as Social Sciences, Biology, and market research to test hypotheses about relationships in categorical data.

What is the difference between correlation analysis and regression analysis?

In linear correlation analysis, we identify the strength and direction of a linear relation between two random variables. Correlation does not imply causation. Regression analysis takes the analysis one step further, to fit an equation to the data. One or more variables are considered independent variables (x1, x2, ... xn). responsible for the dependent or "response" variable or y variable.
