## What do we know about experimentation?

Let's brainstorm in the [Jamboard ](https://jamboard.google.com/d/1iASnxsICB9oHyaCSPYAGAxukEeMkdV-TEeNUnO37l1g/edit?usp=sharing)

## Principles of experimentation

### Goal

Test a causal hypothesis by manipulating one variable and observing change in another variable

### Key elements

.can-edit.key-likes[
* Isolation of the "active" ingredient
* Experimental treatment/manipulation
* Independent variable
* Dependent variable
* Random assignment

## Design considerations

.can-edit.key-likes[
* Who are we sampling?
* Within or between-person experimental manipulation?
* What is an appropriate control?
* How strong is the experimental manipulation?

## Assignment
Design a message framing experiment based on our research question.

These emails will be sent to partner organizations on **April 19**.

1. Form drafting and feedback teams

2. Drafting team: Copy the control email text and modify the message framing by **March 19**

3. Feedback team: Provide feedback on the drafting team's text by **March 26**

4. Randomly assign students to receive the experimental or control email
