E138: Using Employee Surveys and Paired t tests for Measuring Improvement
byBrion Hurley

In this episode, I discuss a specific method for capturing process improvements using surveys, and how you can isolate the improvements so that the difference between survey participants doesn't hide the results.

I also referenced a similar survey I conducted (Episode 77), where I shared the survey results at a company after implementing a daily huddle.

You can check out episode #77 from June 2023 at https://podcasts.apple.com/us/podcast/e77-client-survey-shows-daily-huddles-improve-communication/id1529478357?i=1000615545292
