The science of collecting, organizing, analyzing, and interpreting data to make decisions. It involves two main branches: descriptive statistics (summarizing data) and inferential statistics (drawing conclusions from data).
Front
Categorical Variable
Back
A variable that places an individual into a group or category, such as gender (male/female) or eye color (brown/blue). Arithmetic operations like addition or subtraction do not make sense for these variables.
Front
Quantitative Variable
Back
A variable that takes numerical values representing a measurable quantity, such as height (inches) or temperature (degrees). Arithmetic operations like adding or averaging are meaningful for these variables.
Front
Discrete Variable
Back
A quantitative variable that can take on a countable number of values. Typically, these are integers resulting from counting. For example, the number of pets in a household or the number of cars in a parking lot.
Front
Continuous Variable
Back
A quantitative variable that can take on an infinite number of values within a given interval. These are usually measurements. For example, time, distance, or weight can always be measured more precisely.
