Hi all, I started my winter session meta-analysis course on YouTube!
Join me as I muddle my way through an entire synthesis project. It’s meant as an entry to research synthesis, so expect some lighthearted fun with new posts nearly daily :-)

60 insect pin packets done for my entomology students!
Excited to see what they’ll collect this semester #usf ❤️🦋🐞🦟 🧪

Ecologists love response ratios for meta-analysis❤️
But… they can’t be converted into other effect sizes—making it impossible to have a unified dataset of all published effect sizes in ecology
I fixed this with a conversion to Hedges’ d !!

Here’s an old vid where I outline the problem… I was wrong in so many ways, but articulating the problem out loud help push me take the problem more seriously 😊

Thanks! This is so cool! Maybe I should start reposting again 🤔

Curious about teaching meta-analysis?🤨
Catch my talk about how my approach to teaching this tool has changed throughout the years

Replying to @complete__pi @smartereveryday
Juicr is relatively easy to get the hang of. If using Mac, closing X11 really upsets R Studio, so make sure to save your work before closing X11.

We are in the clear! #Milton did bring some eel riverwash though
As I have a🍺 & wait for #Milton to take my home…
I’m reminded of simpler times, when I decided to post +25 hours of #YouTube videos of me doing a complete meta-analysis from scratch on a topic I barely knew anything about
Do what you love friends!

Meta-analysis is formal & explicit -- don’t get fooled by incomplete applications for synthesizing research
But how do you separate the wheat from chaff?
Here’s a 10min YouTube video of the 3 defining features of a high-quality meta-analysis 💪

A couple of months ago a paper in @science used a "meta-analysis" to summarise the evidence on the success of conservation action. @metanutter & I had a look at the paper and identified a number of issues that are applicable to many such papers 1/11
My research is available on @ResearchGate: researchgate.net/publication…
