Effect Size
Effect size measures how large or meaningful an observed effect actually is.
Unlike p-values, it focuses on practical significance rather than statistical significance alone.
Reporting effect size provides a more complete interpretation of results.

#statstab #535 The Benefits Of Reporting Critical Effect Size Values
Thoughts: You ran a study w/o a power analysis? Report the lowest value your test could have detected at 80% power and 5% alpha.

#statstab #502 Calculate between subjects Cohen's d from frequencies {effectsize}
Thoughts: May come in handy one day, but I'm dubious as to the inference here.

#statstab #461 Interpreting Ordinal and Disordinal interactions
Thoughts: Interactions are not simple things. Their shape can determine many things (including sample size and effect size)

#statstab #413 Counternull Sets in Randomized Experiments
Thoughts: The counternull is a lost statistic, that is woefully underused when teaching stats.

All @BASDBroughalMS teachers are statistically significant, and together we can significantly impact student learning. Let’s go Rockets! #effectsize
#statstab #396 If researchers find Cohen’s d = 8, no they didn’t
Thoughts: Sometimes an effect is so impressive that its unbelievable.

Can’t believe we only have 1️⃣ more NEW TEACHER COHORT session left this year. 😭 SO PROUD of their growth and their dedication to our students. 👏🏼 🎉#effectsize #IsleLEAD #IsleTEACH #IsleLEARN @IWCSchools
#statstab #281 Correcting Cohen’s d for Measurement Error (A Method!)
Thoughts: Scale reliability can be incorporated into effect size computation (i.e., remove attenuation)
