Parametric vs. Non-Parametric Tests & When To Use Built In
WebMar 2, 2024 · A parametric test makes assumptions about a population’s parameters: Normality : Data in each group should be normally distributed. Independence : Data in each group should be sampled randomly and independently. No outliers : No extreme outliers in the data. Equal Variance : Data in each group should have approximately equal variance. WebThe z test can be performed on one sample, two samples, or on proportions for hypothesis testing. It checks if the means of two large samples are different or not when the population variance is known. A z test can further be classified into left-tailed, right-tailed, and two-tailed hypothesis tests depending upon the parameters of the data. outback employee discount
