The chi-square (Χ 2) distribution table is a reference table that lists chi-square critical values. A chi-square critical value is a threshold for statistical significance for certain hypothesis tests and defines confidence intervals for certain parameters.
It can be significantly smaller, but you weren't asking that question. That would be a one-tailed test. For a two-tailed test if the calculated value of t exceeds the tabled value, then report the p value in the table. For a one-tailed test, the p value is divided by two. So 'p . 0.05' becomes 'p 0.025." Find the t critical value if the size of the sample is 5 and the significance level is 0.05. Solution: Step 1: Subtract 1 from the sample size to get the degree of freedom. Degree of Freedom = N - 1 = 5 - 1 Degree of freedom = 4 α = 0.05. Step 2: Depending on the test, choose the one-tailed t distribution table or two-tailed t table belowT Table contains the critical values of the T Distribution. The column contains all the T-Distribution probabilities denoted by "Alpha" or "p". The row contains all the degrees of freedom denoted by "df". Also, here you will get one and two tail T score tables or charts online.To use this T critical value (t table) calculator, enter values in input box. The t table value calculator will instantly give you the t value for one tailed probability as well as two tailed probability. Critical Value Calculator. Use this calculator for critical values to easily convert a significance level to its corresponding Z value, T score, F-score, or Chi-square value. Outputs the critical region as well. The tool supports one-tailed and two-tailed significance tests / probability values.
