Independent or Dependent Variable?

Random Sampling vs. Probability Sampling
Random Sampling-every member of an entire population being studied has the same chance of being selected

example: College students, survey every 5th person that enters library

Probability Sampling-choosing participants for a study on the basis of specific characteristics (age, sex, race/ethnicity, etc.)

example: choosing hispanic females on a college campus for a survey
The number of days since your last haircut
would be an independent variable since it causes a change
The length of your hair
would be the dependent variable since it is changed by the independent variable

The first two would be independent variables because they cause a change. The final grade would be a dependent variable because it gets changed by another variable
The first two would be quantitative because they deal with numerical data. The 3rd study would be quantitative because it deals with attitudes.
