You could ask them to simply categorize their income as high, medium, or low.. For instance, consider a sample of employed individuals. Even though the actual measurements might be rounded to the nearest whole number, in theory, there is some exact body temperature going out many decimal places That is what makes variables such as blood pressure and body temperature continuous. Some other examples are sex (male, female), race (black, hispanic, oriental, white, other), political party (democrat, republican, other), blood type (A, B, AB, O), and pregnancy status (pregnant, not pregnant. For example, social class (in category), gender, and neighborhood all can be considered variables at the nominal level of measurement.

Ratio scale provides the most detailed information as researchers and statisticians can calculate the central tendency using statistical techniques such as mean, median, mode, and methods such as geometric mean, the coefficient of variation, or harmonic mean can also be used on this scale. Discrete data is a sort of numerical data that consists of full, concrete numbers that have particular and fixed data values that are determined by counting. When working with ratio variables, but not interval variables, you can look at the ratio of two measurements. In the following example, weve highlighted the median in red: In a dataset where you have an odd number of responses (as with ours, where weve imagined a small, hypothetical sample of thirty), the median is the middle number. You can also use percentages rather than count, in which case your table will show you what percentage of the overall sample has what color hair. This is the fundamental of quantitative research, and nominal scale is the most fundamental research scale. expressed in finite, countable units) or continuous (potentially taking on infinite values).

For example, a weight of zero doesnt exist; an age of zero doesnt exist. Quantitative data can be used for statistical manipulation.

So if we can determine a variables level of measurement, we can find the statistical tests to be used to reach a conclusion by computing the variable under consideration for a random sample of population. They can be arranged in order (ranked), but differences between entries are not meaningful. Ordinal data is considered as "in-between" qualitative and quantitative data. Eg: class variable for a person can have values like upper class, lower class, middle class etc. Is a shoe brand ordinal or nominal?
