Table of critical values for a 1-tailed F-test at 95% confidence level, generated from Excel using the FINV function.

F-table for Two-Tailed Test at α = 0.05 (95% Confidence Level)

Upper one-sided 0.10 significance levels; two-sided 0.20 significance levels; 90 percent percentiles. Tabulated are critical values for the distribution. The column headings give the numerator degrees of freedom and the row headings the demoninator degrees of freedom.

E Percentile Values χ2p for the Chi-Square Distribution with ν Degrees of Freedom G AND H Values of e-λ ... Spiegel, Murray R., John J. Schiller, and R. Alu Srinivasan. 2013. “95th Percentile Values (0.05 Levels), F0.95, for the F Distribution.” Chap. F in Schaum's Outline of Probability and Statistics.

This calculator will compute the critical values of F-statistics corresponding to nN (numerator) and nD (denominator) degrees of freedom, at the desired probability level. See for example Table 3-1 on page 44 of Stanton A. Glanz "Primer of Biostatistics", 3rd Edition, McGraw-Hill, New York, 1992.

There are two tables here. The first one gives critical values of F at the p = 0.05 level of significance.

Critical Values of the F-Distribution: α = 0.05 · Numerator Degrees of Freedom

Descriptive Statistics Variable ... find a 95% confidence interval for the mean based on the sample mean 98.249 and sample standard deviation 0.733, first find the 0.025 critical value t* for 129 degrees of freedom. This value is approximately 1.962, the critical value for 100 degrees of freedom ...

April 24, 2020 - To calculate a confidence interval ... ... Thus, the 95% confidence interval for the ratio of the population variances is (0.4148, 4.4714)....

To find x using the F-table, we: Find the column headed by \(r_1 = 4\). Find the three rows that correspond to \(r_2 = 5\). Find the one row, from the group of three rows identified in the above step, that is headed by \(\alpha = 0.05\) (and \(P(X ≤ x) = 0.95\).

More specifically, a test statistic is computed with ν1 and ν2 degrees of freedom, and the result is compared to this table. For a one-sided test, the null hypothesis is rejected when the test statistic is greater than the tabled value. This is demonstrated with the graph of an F distribution ...

F Distribution Tables · The F distribution is a right-skewed distribution used most commonly in Analysis of Variance. When referencing the F distribution, the numerator degrees of freedom are always given first, as switching the order of degrees of freedom changes the distribution (e.g., F(10,12) ...

Table of critical values for a 2-tailed t-test at 95% confidence level, generated from Excel using the TINV function.

June 23, 2025 - Use the F-table to find the critical value for your F-test. You’ll need to know the significance level, the numerator degrees of freedom, and the denominator DF.

This calculator will tell you the critical value of the F-distribution, given the probability level, the numerator degrees of freedom, and the denominator degrees of freedom.

Plugging these values into the formula, we get: z = (0.75 - 0.5) / sqrt((0.5 * (1 - 0.5)) / 600) ≈ 5.77 Step 3: Interpretation. The z-score of 5.77 indicates that the sample proportion of 0.75 significantly differs from the hypothesized population proportion of 0.5. The 95% confidence interval ...
