For example, compare whether systolic blood pressure differs between a control and treated group, between men and women, or any other two groups. Don't confuse t tests with correlation and regression. The t test compares one variable (perhaps blood pressure) between two groups. Use correlation and Grubbs’ test can be used to test the presence of one outlier and can be used with data that is normally distributed (except for the outlier) and has at least 7 elements (preferably more).

Hej, jag undrar om ni vet hur man gör Grubbs´ Test i SPSS? Jag vill göra det innan jag du har outliers eller inte. http://graphpad.com/quickcalcs/Grubbs1.cfm.
Molarity Calculators (QuickCalcs) is a web application (no installation required) that helps to dilute a stock solution or to calculate molarity from mass and volume, mass from volume and concentration, volume from mass and concentration. Perform a Grubbs test for outliers. Description: The Grubbs test, also know as the maximum normalized residual test, can be used to test for outliers in a univariate data set. Note that this test assumes normality, so you test the data for normality before applying the Grubbs test. Grubbs test detects one outlier at a time. GraphPad QuickCalcs (Grubbs test) was used to determine statistical outliers, and a t test was used to compare mean insulin levels between high-fat (HF)– and low-fat (LF)–fed mice.

If you suspect more than one outlier may be present, it is recommended that you use either the Tietjen-Moore test or the generalized extreme studentized deviate test instead of the Grubbs' test. May 18, 2010 Prism 6 also has a built-in analysis that can detect outliers using Grubbs' method.
