This can come in the form of web forms, modal pop-ups, or email capture buttons. Quantitative data is made up of numerical values and has numerical properties, and can easily undergo math operations like addition and subtraction. With close-ended surveys, it allows the analysis to group and categorize the data sets to derive solid hypotheses and metrics. Since square footage is a quantitative variable, we might use the following descriptive statistics to summarize its values: These metrics give us an idea of where the center value is located as well as how spread out the values are for this variable.
