A statistical hypothesis test is a method of statistical inference. Subtract Sample Mean by Population Mean, divide Sample Standard Deviation by Sample Size and then divide both the answer in the below Standardized Test Statistic calculator to calculate Hypothesis Test for z-scores. Standardized Test Statistic Calculator. Standardized test statistics are used in hypothesis testing. The general formula formula is: Standardized test statistic: (statistic-parameter)/(standard deviation of the statistic). The formula by itself doesn't mean much, unless you also know the three major forms of the equation for z-scores and t-scores.

If you are comparing two measurements taken on the same sampling unit (e.g. blood pressure of an individual before and after a drug is administered) then the appropriate test is the paired t-test. The test statistic is a z-score (z) defined by the following equation. ${z = \frac{(p - P)}{\sigma}}$ where P is the hypothesized value of population proportion in the null hypothesis, p is the sample proportion, and ${\sigma}$ is the standard deviation of the sampling distribution.

The variance is one of the most important variables in descriptive statics. In the variance calculator, you can easily display the variance or standard deviation of your data.The standard deviation indicates how large the average deviation from the mean value is for your data. Today we calculated the p-value from a given z-test statistic, for a two-sided test, a left-tailed test, and a right-tailed test. For each test, we performed the calculation using three different methods: z-table, graphing calculator, and Excel. Good luck!
