Press the return/enter key to see the result at the bottom of the screen. For example, the 95th percentile of the t-distribution with 29 degrees of freedom (1.699), which is the critical value for an upper-tail test with a 5% significance level.

To find a percentile (critical value) for an F-distribution, type the Command window, where p is the lower-tail area (i.e., one minus the significance level), df1 is the numerator degrees of freedom, and df2 is the denominator degrees of freedom.īy contrast, the 97.5th percentile of the t-distribution with 29 degrees of freedom (2.045), which is the critical value for a two-tail test with a 5% significance level.

To find a percentile (critical value) for a chi-squared distribution, type the Command window, where p is the lower-tail area (i.e., one minus the significance level) and df is the degrees of freedom.įor example, the 95th percentile of the F-distribution with 2 numerator degrees of freedom and 3 denominator degrees of freedom (9.552).To find an upper-tail area (one-tail p-value) for a t-distribution, type the Command window, where t is the value of the t-statistic and df is the degrees of freedom.įor example, the 95th percentile of the chi-squared distribution with 2 degrees of freedom (5.991).For example, the upper-tail area for a t-statistic of 2.40 from the t-distribution with 29 degrees of freedom (0.012), which is the p-value for an upper-tail test.

To find an upper-tail area (p-value) for an F-distribution, type the Command window, where f is the value of the F-statistic, df1 is the numerator degrees of freedom, and df2 is the denominator degrees of freedom.īy contrast, the two-tail area for a t-statistic of 2.40 from the t-distribution with 29 degrees of freedom (0.023), which is the p-value for a two-tail test. To find an upper-tail area (p-value) for a chi-squared distribution, type the Command window, where chisq is the value of the chi-squared statistic and df is the degrees of freedom.For example, the upper-tail area (p-value) for an F-statistic of 51.4 for the F-distribution with 2 numerator degrees of freedom and 3 denominator degrees of freedom (0.005). Type the name of the quantitative variable into the Objects to display in a single window box and click OK.Ĭalculate descriptive statistics for a quantitative variable by selecting Quick > Show.For example, the upper-tail area (p-value) for a chi-squared statistic of 0.38 for the chi-squared distribution with 2 degrees of freedom (0.827). #Buy eviews 9 student version software#.
