F-Test calculator calculates the F-Test statistic (Fisher Value) for the given two sets of data $X$ and $Y$. It's an online statistics and probability tool requires two sets of real numbers or valuables. It is necessary to follow the next steps: Enter two samples (observed values) ...
The test statistic is {eq}\chi^{2}=0.264+0.021+0.913+0.048+0.264=1.51. {/eq} For a Chi-Square distribution with 5-1=4 degrees of freedom, we compute the p-value using an online calculator (such as https://www.statology.org/chi-square-p-value-calculat...
A t-test uses the test statistic, sometimes called a t-value or t-score, the t-distribution values, and the degrees of freedom to calculate the statistical significance of the difference. Since a t-test is a parametric test, it relies on assumptions about the process that generated the ...
From the calculator, we see that the test statistic (T) is 8.91505. Assuming equal variances in groups and given a significance level of 0.05, the probability of observing a test statistic (T) bigger than 8.91505 is given by the P-value. Since the P-value (0.06326) is bigger than the ...
Depending on the test you run, you may see other statistics that were used to calculate the P value, including the mean difference, t statistic, degrees of freedom, and standard error. The confidence interval and a review of your dataset is given as well on the results page. ...

A chi-squared test is any statistical hypothesis test in which the sampling distribution of the test statistic is a chi-squared distribution when the null hypothesis is true. Chi Square FormulaX2 = ∑ (Observed Value-Expected Value)2 (Expected Value) ...
Step 6:Find the critical value at a confidence level of 95% for degrees of freedom 9, i.e., 2.262. Result: Quick Reference Snapshot for all Types of t-Tests t-Test Formula Calculator You can use the following t-test Formula Calculator. ...
the sample mean of 011242432014061112and 017551892 is 0.02076634.3 Having obtained the -test statistic using a hand-calculator, we need tables of the F-distribution in order to obtain the corresponding -. The F- distribution is very similar in shape to the Chi-square distribution.4 However, ...
