https://www.ecalculator.co/calc/t-value-calculatorFor the alpha level 0.025, and degrees of freedom 4, the critical value of t will be 2.776.. T critical value = 2.776. Moreover, you can use our t value calculator to find the t value at one click.. How to find z critical value? Example: We will assume significance level (α) of 0.03 to find the z critical value for two tailed test.. Step 1: Divide the significance level by 2.
Norm-Scale-Calculator by Psychometrica
www.psychometrica.de › normwertrechner_enThe Norm Score Calculator also offers the transformation into z-scores (M = 0, SD = 1), T-scores (M = 50, SD = 10), Standard Values (SW score; a norm scale used in German speaking countries; M = 100, SD = 10), and Wechsler Subscale Scores (M = 10, SD = 3). Percentiles, on the other hand, provide a different kind of information.
