How to Run a Successful Experiment
1. One test at a time. Keep it simple. Don’t try to test too many new variables at once, or your results will not be meaningful. Change one thing and one thing only, trying to keep everything else the same, and see what happens.
.
2. Define your outcome variables. What do you want to measure? Try to keep the things you measure to a minimum too – identify the one or two things you really want to change and see if they are changing.
.
3. Repeat Experiment. One trial is not enough to get accurate data. Repeat at least three times
