WebThis critical values calculator is designed to accept your p-value (willingness to accept an incorrect hypothesis) and degrees of freedom. The degrees of freedom for a t-distribution can be derived from the sample size - just subtract one. (degrees of freedom = sample size - 1). You can use this as a critical value calculator with sample size. WebApr 14, 2024 · Step 1: Calculate the test statistic using raw data. Step 2: Compare the test statistic to the t critical value (tα/2). Step 3: Reject or fail to reject the null hypothesis of the test. If the absolute value of the t test statistic is greater than the t critical value, then we can reject the null hypothesis of the test.
