Dear All,
You are invited to join the upcoming Mellenbergh lecture on Wednesday, June 10th! Professor Andy Field will talk about the use of OLS models in psychology.
Speaker: Professor Andy Field, Professor of Quantitative Methods at the University of Sussex, UK (yes, the stats book guy!)
Title: Statistical Practice in Psychology: The Numbers of the Beast
Abstract: Ordinary Least Squares (OLS) estimation is commonly used in psychological research to analyse data from a range of research designs. This talk explores the performance of OLS estimation under real world situations. I look at data showing that in practice Psychology researchers routinely collect data that is a challenge for OLS estimation. Furthermore, I show that OLS performs poorly compared to other estimation methods. I then shine the spotlight on research practice using data suggesting that Psychology researchers do not fully understand the conditions under which OLS models perform well. It turns out that they also do not attend fully to these conditions in their own work or when faced with a new analytical challenge! After this relentless barrage of negativity I will try to finish on a note of positivity by exploring some ways to improve statistical practice. Time and Place: June 10th, 11:00 - 12:00, Room M1.02
