Log Transformations in SPSS

This video tutorial demonstrates how to perform log transformations on data using SPSS. It begins with an introduction to log transformations, followed by a detailed guide on executing a log10 transformation. The tutorial then explains how to perform a log transformation with a different base, specifically base 2, using SPSS. The process involves using the 'Transform' and 'Compute Variable' functions in SPSS, and the video provides step-by-step instructions for each type of transformation.
