Biology Chi Square Critical Value Table. The chi square χ 2 distribution is often used in. The x2 distribution table represents a theoretical curve of expected results.
Use the critical values table to determine if the calculated value is equal to or less than the critical value. The final calculated chi square value is determined by summing the values. State the null hypothesis.

Critical values of the chi square distribution at p 0 05 0 01 0 001 for d 1 20 degrees of freedom the critical value of a statistical test is the value at which for any per determined probability p the test indicates a result that is less probable than p. The x2 distribution table represents a theoretical curve of expected results. Since our test statistic is smaller than our critical value we fail to reject the null hypothesis. Critical value using the degrees of freedom determine the critical value using the provided table df 1 critical value 3 84 biologists generally reject the null hypothesis if the value of p is less than 0 05.
