Test Statistic Comparing Two Means CalculatorMean of x, x: Mean of y, y: Standard deviation of the x values, σx: Standard deviation of the y values, σy: Sample Size of the x values, n1: Sample Size of the y values, n2: Test Statistic Comparing Two Population Means: This...
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 ...
A t-statistic of 2 or greater is typically enough to confirm statistical significance in the social and biological contexts.Recommended Statistics Resources Winning Percentage Calculator Standard Error Calculator Average Calculator Central Limit Theorem Calculator T Table ...
We want to use these results to test $H_0: \mu_1=\mu_2$ versus $H_a: \mu_1\ne\mu_2$. Find the test statistic for this test. The t-test calculator, work with steps, formula and practice problems would be very useful for grade school students (K-12 education) to learn what ...

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, ...
Test statistic F = MSG MSE F distribution Assumptions Independent observations (no repeated measure) The dependent variable is continuous (ratio or interval) The independent variable is categorical, contains the groups' name. The residuals distribution is normal, or sample size of 30 or more and re...
Using a Chi-square distribution table with DF=1 and χ2=0.116884, our test statistic falls between the values of 0.00016 and 1.642, which have p-values of 0.975 and 0.2, respectively. Our p-value must lie between these values. Using an online p-value calcul...
Test statistic Distribution of test statistic Decision rule Calculation of test statistic: The results of the arithmetic calculations is summarized in a table called the analysis of variance (ANOVA) table. The entries in the table make it easy to evaluate the results of the analysis. Statis...
This Fisher's exact test calculator computes both the one-tailed and two-tailed p-value for a Fisher's exact test on any 2 x 2 contingency table. To compute the p-value of other statistical tests, visit our p-value calculator. Not sure what Fisher's exact test is? Are you wondering ...
