Using TELLab, you will design and implement an online experiment to test some hypothesis of your own design related to visual search.Quantitative experiments (e.g., A/B tests) are great, but they are actually very hard to design such that the data can be trusted. In the process of designing your own experiment, you will learn how to be paranoid about accidentally introducing confounds into your experimental design.  You will work in teams of 3-4 (these can be, but do not have to be, your project 2 teams).

Bring your laptop!
