WebSep 11, 2024 · 16.4: Critical Values for t-Test. Assuming we have calculated texp, there are two approaches to interpreting a t -test. In the first approach we choose a value of α for rejecting the null hypothesis and read the value of t(α, ν) from the table below. If texp > t(α, ν), we reject the null hypothesis and accept the alternative hypothesis. WebNote: To calculate t critical value, f critical value, r critical value, z critical value and chi-square critical use our advance critical values calculator. It helps to calculate the value from the Z table very quickly in real-time. Common confidence levels …
