WebThe critical value in statistics is the measurement statisticians use to quantify the margin of error within a collection of data, and it is represented as: Critical Value = 1 - (Alpha / 2) where, Alpha = 1 - (confidence level / 100). WebThe critical value for a one-tailed or two-tailed test can be computed using the confidence interval. Suppose a confidence interval of 95% has been specified for conducting a …
