This article was discussed in the lesson as an example of researchers who conducted factor analysis on an existing measure. This may be helpful to view an example of this process and how to articulate the results.

Qualtrics. (2022). What is factor analysis and how does it simplify research findings?
When you collect your data, you can then enter the data into an Excel file and then transfer into SPSS. Another way to do this, that saves time, is to use a survey tool such as Qualtrics. In Qualtrics, you can write your instrument questions and answer choices, give the link to participants, and they answer the questions directly in Qualtrics. Then, you can download the Excel file without having to input all the data yourself. This resource walks you through how to also use Qualtrics to conduct factor analysis.
