Does anyone know what Chi^2 is? and if the smaller or larger number is better when computing data...I can't find an answer on the web

Chi-square test is a statistical method used to analyze categorical data. It is used to determine whether there is a significant relationship between two variables.
The Chi-square test statistic is calculated by taking the sum of the squared differences between the observed and expected frequencies of the data, divided by the expected frequencies.
A higher Chi-square value indicates a larger difference between the observed and expected frequencies, and therefore a stronger relationship between the variables. However, the significance of the relationship also depends on the sample size and the degrees of freedom.
A significant Chi-square result indicates that there is a low probability that the observed relationship between the variables is due to chance. This means that there is a significant relationship between the variables being studied.
No, Chi-square test is only appropriate for categorical data. It cannot be used for continuous data or data that is measured on a numerical scale.
