Q: Does the Kaiser-Meyer-Olkin (KMO) value and the Bartlett's test of sphericity to determine appropriateness for factor analyses impact the validity of a study?

Thanks for your query. We have shared this with our methodology and business experts, and shall get back shortly. From what we know though, yes, the KMO and Bartlett’s test do impact the validity of the study. If the value is less than 0.50, then the results of the factor analysis probably won’t be useful. However, we’ll wait to see if our experts have more to add to this. In the meantime, feel free to look around the forum and also the site for other topics of interest.
