Hypothesis Test Calculator Online. One sample t-test Unpaired t-test Paired t-test und Chi-square test. A t -test is used when youre looking at a numerical variable - for example height - and then comparing the averages of two separate populations or groups eg. You will also find tutorials for non-parametric statistical procedures such as the Mann-Whitney u-Test and Wilcoxon-Test. So for example it could be used to determine whether the mean diastolic blood pressure of a particular group differs from 85 a value determined by a previous study.
Then hit Calculate and the test. The statistical test for an experiment mainly depends on the nature of the independent and dependent variables analyzed. That the two samples are independently and randomly drawn from the source. Fill in the sample size n the number of successes x the hypothesized population proportion p 0 and indicate if the test is left tailed or two tailed. Test Statistic Calculator Paired t-test Calculator Unpaired t-test Calculator T-value Calculator p-value Calculator Variance Calculator. In the Hypothesis Test Calculator you can easily calculate a t-test a chi-squared test a binomial test or an analysis of variance.
A tool perform calculations on the concepts and applications for Hypothesis testing calculations.
If you need a more detailed explanation you will find more. For hypothesis tests about the population mean μ the test statistic is z x μ 0 σ n if the population standard deviation σ is known and t x μ 0 s n if σ is unknown. Enter the sample mean population mean sample standard deviation population size and the significance level to know the T score test value P value and result of hypothesis. Then hit Calculate and the test. So for example it could be used to determine whether the mean diastolic blood pressure of a particular group differs from 85 a value determined by a previous study. It helps you build a mechanism for making quantitative decisions about a process.
