Citizen science for small sample size research!

[mightymetrika @mightymetrika]

Small-sample research is everywhere, but the methods actually designed for it? Basically ghosts. 👻📊

We need to learn these methods faster, and the best way is together. What if we treated statistical exploration like citizen science? (Think eBird, but for stats 🦅🔬).

In this thread, we use a Replext app from mightymetrika to crowdsource, replicate, and extend a method called "informative hypothesis testing."

Let’s dive in! 🧵👇

It is important to carefully consider individual level data when working with small sample sizes!

#rstats #statistics #math #dataanalysis #analytics #ml #ai

[mightymetrika @mightymetrika]

Group averages can lie. 📉

In small-sample longitudinal studies, looking only at the mean can hide the real story.

Visualizing individual trajectories reveals hidden heterogeneity, non-linear trends, and critical outliers. Here’s a practical tool from Carrig, Wirth, & Curran (2004; 10.1207/S15328007SEM1101_9) to fix that.

P-values can hold your small-sample studies back. 📉

“Not significant” ≠ “No effect.”

Bayes factors fix this. They let you weigh the evidence for multiple plausible hypotheses at once—including your theory vs. the null. It’s time to upgrade how we measure evidence.

Hard to collect a large sample size for your #clinical intervention #research? 🧐

Single-Case Experimental Designs (SCEDs) are a powerful alternative! Participants serve as their own controls, measured repeatedly over time [Maric, Marija & Werff, Vera. (2020). Single-Case Experimental Designs in Clinical Intervention Research. 10.4324/9780429273872-9]

Note: To meet strict WWC 5.0 standards, a well-designed SCED needs built-in replication (like an ABAB #design), not just a simple A-B phase. [https://t.co/yJ6CmZ4wq6]

But regardless of the specific design, how do we validate that our data shows a meaningful, reliable effect? Enter: The Non-Overlap of All Pairs (NAP).

Does an effect hold for everyone the sample, or just on average? 🤔 Detecting a group-level effect doesn't guarantee it applies to every individual. Klaassen (10.4324/9780429273872-11) proposed a method to evaluate hypotheses case-by-case and aggregate the results. 🧵👇 #RStats

[Indie Game Joe @IndieGameJoe]

This game dev is making a game where you fly through a semi-open world as a paper plane. Wow!

- Transform between a plane, ball, or boat in real-time
- Realistic physics
- Unlockable upgrades

The game is called Paper Sky. Release date TBA.

ブーメランアクションゲーム試作してみた。投げっぱなしにすると徐々に火力が増すブーメランを、ジャグリングのように空中で踊らせながら戦う。
自身にブーメランがぶつかると吹っ飛んで加速し、攻撃だけでなく移動アクションの幅も広がるのが特徴。

画面枠を動かしてボールを上下左右にループさせる、ブロック崩し風ゲームを試作してみた。窓から覗いて空間を切り出すような感触が特徴。
跳ね回るボールを眺めて楽しみつつ、ボールの流れをループで制御しフィールドの隅々まで巡らせていく。

@lu_sichu Wow!

[mightymetrika @mightymetrika]

Sometimes theory says "positive effect " but regression output says "p-value for not zero". Avoidable?

Wolak's 87 paper (10.1080/01621459.1987.10478499) gives exact tests for inequality constraints.
