chi square critical value in r
# Define the significance level
alpha <- 0.05
# Define degrees of freedom
df <- 4
# Calculate the chi-square critical value
chi_critical <- qchisq(1 - alpha, df)
chi_critical
Explanation:
- Set the significance level (alpha) to 0.05, indicating a 5% significance level for the chi-square test.
- Define the degrees of freedom (df) as 4, which is a parameter needed for chi-square distribution calculations.
- Use the
qchisq
function in R to compute the chi-square critical value (chi_critical
) corresponding to a given significance level (1 - alpha
) and degrees of freedom (df
). - Output the calculated chi-square critical value.
