Consumer Reports is doing an article comparing refrigerators in their next issue. Some of the characteristics to be included in the reports are the brand name and model; whether it has a top, bottom, or side-by-side freezer. the estimated energy consumption per year (kilowatts); whether or not it is Energy Star compliant; the width, depth, and height in inches, and both the freezer and refrigerator net capacity in cubic feet. Which of these variables are categorical and which are quantitative? Give the units for the quantitative variables and the categories for the categorical variables. What are the individuals in the report?

    The categorical variables are: Brand and model (nominal category, has no hierarchy or name); it has a freezer (categorical nominal, upper, lower, or side to side); complies with Energy Star (binary categorical, true or false)

    The quantitative variables are: Estimated energy consumption per year (kilowatts); width (inches); depth (inches); height (inches); net refrigerator capacity (cubic feet); net freezer capacity (cubic feet).

    Individuals are potential buyers

    Step-by-step explanation:

    The categorical variable is the one used to assign a non-numerical or qualitative characteristic or property to some object, individual, entity, condition or procedure. The main characteristic of categorical variables is that unlike other variables, such as continuous and discrete variables, it is not possible to make arithmetic with them.

    Quantitative variables are those variables that give a result represented by a numerical value. They are generally used in surveys or interviews. They make use of graphs to show the relative frequency of these variables. You can also use bar diagrams when giving figures.
