Sample Mean, x: Standard deviation, σ: Sample Size, n: Test Statistic for One Population Mean: The Test Statistic for One Population Mean Calculator is a calculator that is used when the variable is numerical and only one population or group is being studied. ...
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) ...
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. ...
Welcome to our t-test calculator! Here you can not only easily perform one-sample t-tests, but also two-sample t-tests, as well as paired t-tests. Do you prefer to find the p-value from t-test, or would you rather find the t-test critical values? Well, this t-test calculator ca...
Find the P-Value The next step is to find the p-value for the test statistic. The p-value is a measure of how “surprising” or “unlikely” some statistic would be given the particular assumptions that the analyst makes. In the case of these t-tests for differences in means, the p...
If you are also interested in F-test, check our F-statistic calculator. What is a Z-test? A one sample Z-test is one of the most popular location tests. The null hypothesis is that the population mean value is equal to a given number, μ0μ0: H0: μ=μ0.H0: μ=μ0. We...
t-Test Calculator is a tool used to determine whether there is a statistically significant difference between the means of two independent groups. What is a t-Statistic? The t-Statistic is a value derived from your sample data that measures the size of the difference relative to the variation...
The test statistic H is calculated based on the ranks of the combined data from all samples. How to Calculate the Kruskal-Wallis H Statistic The Kruskal-Wallis H statistic is calculated using the following formula: H=12N(N+1)∑i=1kni(Ri−R¯)2 Where: N = Total number of observat...
Step 4: Using the found test-statistic and a Normal distribution table or calculator, find the corresponding p-value. What are a Test-Statistic and P-value? Test-Statistic: When performing a statistical test, we are interested in calculating a number. This number help...
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-calculato...
