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...
T-Test Calculator Compare the means of two samples using a single-sample or two-sample t-test below. Results: Two-tailed P: Left-tailed P: Right-tailed P: Test Statistic (t): Degrees of Freedom (df): Learn how we calculated thisbelow...
How to calculate p-value in the context of a z-test? The answer depends on whether you are using a two-tailed, a left-tailed or a right-tailed test. Say you have the calculated z-statistic,ZobsZ_{obs}Zobs. For a two-tailed test, the p-value is computed as:p=Pr(Z>∣...
Test Statistic Comparing Two Population Means: This Test Statistic Comparing Two Population Means Calculator calculates the test statistic when comparing two population means. This test is used when the varaible is numerical (for example, cost of goods, earnings, stock price) and two populations or...
Our McNemar's test calculator will return the p-value, based on which you can decide if your findings are significant at the desired significance level. Additionally, for tests based on the χ² test statistic, our McNemar's test calculator displays the value of test statistic so that you ...
The two-tailed p-value generated from the calculator is 0.0557. Using 0.05 as our threshold for significance, strictly speaking, we would conclude there is NOT a statistically significant difference between designs using the Fisher exact test. In applied use, we’d likely come to the same conclu...

Find the P-value for a right-tailed test with n = 18 and test statistic t = 2.723. Find the p-value for a right-tailed test with n = 15 and a test statistic of t = 3.936. Using the t tables, software, or a calculator, estimate ...
1 = 2 using the table, the critical value for a 0.05 significance level with df = 2 is 5.99. that means that 95 times out of 100, a survey that agrees with a sample will have a χ 2 value of 5.99 or less. the chi-square statistic is only 0.7533, so we will ...
P-value = 0.00990 * 2 = 0.0198 That p-value is an approximation because it uses a Z-score of 2.33 rather than 2.333. Using an online calculator, the p-value for our Z test is a more precise 0.0196. This p-value is less than our significance level of 0.05, which reconfirms the sta...
