Test Statistic for a Single Population Proportion CalculatorSample Proportion, ṗ: Claimed Proportion, p0: Sample Size, n: Test Statistic For a Single Population Proportion: The Test Statistic for a Single Population Proportion calculates the test statistic when the variable is categorial (for ...
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...
The proportion test compares the sample's proportion to the population's proportion or compares the sample's proportion to the proportion of another sample. One sample proportion test (Go to the calculator) We use this test to check if the known proportion is statistically correct, based on the...
The 'Proportion Test' is a statistical test used in the field of Computer Science to compare two proportions. It calculates a test statistic that is then used to find the p-values, which determine the significance of the results. The test is based on the formula ( p ^ 1 - p ^ 2 )...
2-PROPORTION Z TEST This test is used to compare proportions from 2 independent samples.In s study done in Michigan, it was determined 38 (out of 62) poor children who attended pre-school needed social services later in life compared to 49 (out of 61) poor children who did not attend ...

An AB test (also known as a split test or a two-proportion statistical significance test) is a form of Z-test. Our Z-test's null hypothesis (the default assumption) is that the two proportions are the same. We want to prove the null hypothesis wrong; we want to prove that there is...
Research questions involving differences in independent and dependent population proportions can be tested using a z-test statistic. Unfortunately, these types of tests are not available in most statistical packages, and therefore you will need to use a calculator or spreadsheet program to conduct the...
You can download this sheet as Excel and use it as a fast and easy z-test calculator. Given 2 sample proportions and 2 sample sizes, our tool checks if the sample size assumption is met; computes the 2-tailed-significance-level for the z-test; computes a confidence interval for the diff...
About t-Test Calculator 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...
