Fisher's Exact Test with Plain-English Interpretation

Usage

fisher_interpret(x, y, conf.level = 0.95, simulate.p.value = FALSE)

Arguments

x: A factor or character vector (first categorical variable)
y: A factor or character vector (second categorical variable)
conf.level: Confidence level. Default 0.95.
simulate.p.value: Logical. Whether to use simulation to compute p-values for larger tables. Default FALSE.

Value

An object of class statease_fisher containing test results and interpretation. Use print() to display the formatted report.

Examples

x <- c("Yes","No","Yes","Yes","No","Yes","No","No","Yes","Yes")
y <- c("Male","Female","Male","Female","Male",
       "Female","Male","Female","Male","Female")
result <- fisher_interpret(x, y)
print(result)
