oTree Tutorial (Updated for 2021)

We are happy to announce our updated tutorial series on oTree, which is an open-source platform for behavioral research. The tutorial is a three-part series created for doctoral students and researchers who are interested in using oTree for their survey and experimental research.

Running your experiment on MTurk

With the increasing popularity of online experiments, many have asked us for advice on how to conduct experiments on Amazon's Mechanical Turk. In this post, Christian Peters provides a hands-on guide.

The best time to pick up oTree (to design interactive experiments) is now!

Over the past few months, oTree has undergone changes making it much easier to design your (online) interactive experiment. Find out what changed!

Deploying your experiment to a server

The consequences of the Coronavirus have made it impossible to run experiments in the laboratory. This post shows how you can launch your experiment to participants on the internet.

Using animations in your instructions

This post present an easy way to support your textual instructions with animations.

Eliciting process variables using scripts

This post shows how you can elicit process variables in an unobtrusive way using scripts.

Sliders with feedback and without anchoring

Sliders are a great way to elicit input from participants. In this post, I share a few lines of code helping you program sliders with real-time feedback and without anchoring.

Embedding excel spreadsheets in your experiment

Some experiments ask participants to make use of Excel spreadsheets. This post shows how to embed Excel spreadsheets in the code of your experiment.

Four amazing oTree apps

In this post, I showcase a risk elicitation procedure, two real effort tasks, the slider task, and SVO measures for oTree, which is an open-source platform for experiments, laboratory studies, field studies, and surveys.
