Statistical method for assessing relationships between categorical variables using observed and expected frequencies. Contingency Table
Grid organizing observed frequencies for two categorical variables, facilitating calculation of totals and expected values. Observed Frequencies
Actual counts recorded in each cell of a contingency table, representing real-world data for categorical variables. Expected Values
Calculated frequencies for each cell, derived from row and column totals, assuming variables are independent. Row Total
Sum of observed frequencies across a single row in a contingency table, representing one category of a variable. Column Total
Sum of observed frequencies down a single column in a contingency table, representing one category of a variable. Grand Total
Overall sum of all observed frequencies in a contingency table, used in expected value calculations. Null Hypothesis
Statement asserting no association between variables, serving as the default assumption in independence testing. Alternative Hypothesis
Statement suggesting a relationship or dependence between variables, tested against the null hypothesis. P-value
Probability measure indicating the strength of evidence against the null hypothesis in statistical testing. Significance Level
Threshold for deciding whether to reject the null hypothesis, commonly set at 0.05 in hypothesis testing. Categorical Data
Data type representing distinct groups or categories, often used in contingency tables for independence tests. Homogeneity Test
Statistical procedure similar to independence testing, comparing distributions across different populations. Hypothesis Testing
Framework for making inferences about population parameters based on sample data and statistical evidence. Excel Function
Built-in tool in Excel, such as =CHISQ.TEST, automating statistical calculations for independence tests.
