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 :-) youtu.be/rM4MQA5hU6c – at Tampa, FL

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 !! Link to paper below:

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 😊 youtu.be/a4D-DSKE2J8?si=Gthr… via @YouTube

There is tremendous risk in repeatedly analyzing data as it comes in… For example, in the absence of any effect, the p-values of repeated t-tests on a growing dataset will randomly walk between 1 and 0! Thanks to @lakens for inspiring this simulation! #RStats #dataviz

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

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. youtu.be/tiL-gZgN9Qk?si=KZs1…

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! youtu.be/rM4MQA5hU6c?si=BDii…

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 💪 youtu.be/3XkC_jetn-U

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
