    Discrete variables go in steps, and nothing in between. For example, the number of people in a household is a discrete variable, because there cannot be 3.3 people in the house.

    discrete variables have possible outcomes that are countable

    Put pi in front of everything to figure this out Can you have: pi # of votes? No pi as a telephone number or digit? No pi temperature? Yes pi Speed? Yes pi Weight? Yes If something is continuous, it is not discrete. Discrete values are not continuous.

    Well, maybe decimals would be a better thing to use than pi

    Can you express # of votes as a decimal? No Telephone number as a decimal? No Temperature as a decimal? Yes Speed as a decimal? Yes Weight as a decimal? Yes If it can be expressed as a decimal, then it is not discrete. If it can't be expressed as a decimal, then it is discrete. You can use that as a general guideline. It may not apply to every and all situations.

    "It may not apply to every and all situations. " it doesn't discrete just means countable possible outcomes. it is possible for a variable to have outcomes that are rational numbers...this would be a discrete variable (even though you have decimals)

    I see what you mean. The ultimate question to ask is, "Is whatever you are measuring countable?". If yes, it is discrete, if not, then it is not discrete.
