QI Macros also makes it easy to run Auto Correlation and Covariance tests. Sample 2 and Sample 3 have a negative correlation (-.608).Sample 1 and Sample 3 have a negative correlation (-.07).Sample 1 and Sample 2 have a positive correlation (.414).If the correlation is greater than 0.80 (or less than -0.80), there is a strong relationship. -1 to 0 to 1 = Positive Correlation (more of one means more of another).Click on QI Macros > Statistical Tools > Regression and Other Statistics > Correlation:Ĭorrelation Results will always be between -1 and 1.This sample data is found in QI Macros Test Data > statistical.xlsx > Correlation-Covariance tab Example of correlation analysis using QI Macros Excel add-in.Ĭlick and drag over two or more columns of data: Does it increase or decrease with weight?Įxcel's data analysis toolpak provides tools to analyze the variance (i.e., covariance) and relationships (i.e., co-relation) between two or more sets of numbers but it can be difficult to use. To activate, go to File -> Options -> Add-ins and then activate the. Data Analysis ToolPak is not available by default, and you need to activate the add-in separately.
