Define: inference, observation, hypothesis, dependent variable, independent variable, theory.
Inference is a guess; observation is a theory.
Hypothesis is a theory; observation is a guess.
Observation is gathering data; hypothesis is a testable statement.
Theory is a guess; dependent variable is a constant.
Given a scientific scenario, can you identify the IV, DV, constants, and control variables?
