or producing goods or services for payment or as volunteers
HYPOTHESIS TESTING
Make a prediction about the way users will perform with your design
VARIABLES
Independent variable (IV): what you are changing between iterations
Dependent variable (DV): what you are measuring
Control variable: a circumstance (not being tested) that is kept constant throughout (
