Science Buddies: "Ask an Expert"

if im doing my project and if you can determine a real or fake smile what would be my independent and dependent variable??

Hello there,

If I understand correctly, your experiment is on whether or not it is possible to determine if a smile is fake or not. In that case, your independent variable would be the fake or non-fake smile and your dependent variable would be whether or not you were able to determine if it was fake or not...
This seems to be a difficult experiment to conduct/scientifically test but maybe you can use different groups of people, etc. to carry out your experiment...
If you can provide more information on your project, it would help to answer your questions...

All the best
