Quantitative variables represent amounts of things (e.g. the number of trees in a forest). Types of quantitative variables include: Continuous (aka ratio variables): represent measures and can usually be divided into units smaller than one (e.g. 0.75 grams).
Quantitative data may be either discrete or continuous. All data that are the result of counting are called quantitative discrete data. These data take on only certain numerical values. If you count the number of phone calls you receive for each day of the week, you might get values such as zero, one, two, or three. Quantitative variables, also known as numerical variables, quantify observations and can be counted or measured (Creswell & Creswell, 2018). Quantitative variables contrast sharply with qualitative variables, the latter of which classify data into predefined groups without quantities or measures attached to them.Quantitative variables involve a numerical output .One Quantitative Variable, Multiple Groups: Variable name: Input: Group Name: Input data separated by commas or spaces.

There are a variety of ways quantitative variables can exist and, thus, be properly measured. One way they can differ is by being discrete variables or continuous variables. Discrete variables are sometimes referred to as discontinuous variables. When a quantitative variable is discrete it means it exists and can be measured in counts. The data .Quantitative variables are measured with some sort of scale that uses numbers. For example, height can be measures in the number of inches for everyone. Halfway between 1 inch and two inches has a meaning. Anything that you can measure with a number and finding a mean makes sense is a quantitative variable. . One Possible Solution: The three .
