This article describes how to create a distance matrix, also known as a dissimilarity matrix. A distance matrix is a table that shows the distance between pairs of objects. You can compare variables or the values of up to 100 individual cases.
A data set containing two or more variables of the scale (numeric, ordinal, etc.) to use as inputs to the distance matrix.
- From the toolbar select Create > Correlation > Distance Matrix.
- From the object inspector on the right, select Inputs > Compare and select if you want to compare variables or cases. For this example, we'll select variables.
- For Inputs > Variables, select the variables to compare.
- Click the Calculate button to generate the distance matrix output.
