You're probably used to the word "variable" in algebra. Letters like x and y are used in place of numbers. Twotypes of variables are used in statistics: Quantitative and categorical. Quantitative variables are numerical: counts, percents, or numbers. Categorical variables are descriptions of groups or things, like "breeds of dog" or "voting preference".Examples of Quantitative Variables:High school Grade Point Average.Number of pets owned.Bank account balance.Number of stars in a solar system.Average number of lottery tickets sold.How many cousins you have.The amount in your paycheck.General rule: if you can add it, it's quantitative. For example, a G.P.A. of 3.3 and a G.P.A. of 4.0 can be added together (3.3 + 4.0 = 7.3), so that means it's quantitative.Examples of Categorical Variables:Class in college (freshman, sophomore, junior, senior).Party affiliation (Republican, Democrat, Independent).Type of pet owned (dog, cat, rodent, fish).Favorite author.Preferred airline.Hair color.Your race.Types of hats.As a general rule, if you can't add something, then it's categorical. For example, you can't add cat + dog, or Republican + Democrat.
