Types of Variables u Quantitative or numeric variables: u Equal-Interval variable: Differences between scale points reflect equivalent amounts of the thing being measured across the entire scale u (dollars in my right now, temperature in degree) u Ratio-scale variable: An equal-interval variable with a "true zero". Examples include: The following table summarizes the difference between these two types of variables: Use the following examples to gain a better understanding of categorical vs. quantitative variables. Conclusions drawn from quantitative research are only applicable to the particular case studied, and any generalized conclusions are only hypotheses. For example, the difference between high school and 2-year degree is not the same as the difference between a master's degree and a doctoral/professional degree. One of the most common and well-known categories of data is quantitative data, or data that can be expressed in numbers or numerical values.

The trick is to get a handle on the lingo right from the get-go, so when it comes time to work the problems, youll pick up on cues from the wording and get going in the right direction.
\nQuantitative variables
\nQuantitative variables are measured and expressed numerically, have numeric meaning, and can be used in calculations. Qualitative data is descriptive data that is not expressed numerically. Hair color 4. Quantitative data lends itself to statistical analysis; qualitative data is grouped and categorized according to themes. Sometimes, however, we will need to consider further andsub-classifythese variables as defined above. Together we discover. << /Length 10 0 R /Filter /FlateDecode /Type /Pattern /PatternType 1 /PaintType Ratio data is similar to interval data in that its equally spaced on a scale, but unlike interval data, ratio data has a true zero.

Collecting data this way is often referred to as structured, in which the focus is on observing, rather than adding up and measuring behaviors. Differences are not precisely meaningful, for example, if one student scores an A and another a B on an assignment, we cannot say precisely the difference in their scores, only that an A is larger than a B.
