critical value

Share This

“In hypothesis testing, the critical value is the point at which the null hypothesis is rejected. The value is found from the distribution function or tables. With standard normal data, common critical values are 1.96 for a two-tailed test at 5 percent error, and 2.58 for a two-tailed test at 1 percent error. In Excel, NormSInv(probability/2) and TInv(probability, degrees of freedom) provide the critical values for the standard normal and T distribution. “
