I just want to point out to those who are excited about confirming their preconceived bias that MBAs don’t matter: according to this result, MBA CEOs outperformed non MBA CEOs by 0.04% per month. That’s quite a bit of alpha.
EDIT: yes, the individual means are not statistically significant but given the large effect
a) where is the p-value
b) there is no statistical significance reported of the difference between MBA and non-MBA performance, only of individual means
- Sebguer 8y agoExcept... the study also points out that this is not a statistically significant difference. How do you miss that?
- vasilipupkin 8y agoI didn’t. Statistical significance is complicated. In a noisy data set, you have to also look at the magnitude of the effect - and its huge here. Note that they don’t report p-value magnitude, which matters. They also don’t report statistical significance of difference, only of individual effects.
