Surveys, Experiments, and Observational Studies

In a survey you select people

• That you know and are very familiar with

• who think like you do

• randomly

Surveys are

• quick and don't take much time to do

• slow and take a long time to do

Surveys can give biased or skewed data so it is important to

• stare someone directly in the eye as you ask the question

• word your question carefully so you get the least biased responses possible.

A helpful thing about observational studies is that

• You can get more detailed information 

• You get to stalk people in the name of science
