Variables are measured using Instrument, equipment or computer. The scale of the measured variable greatly affects the types of analytical techniques available to the data, and the conclusions that can be drawn from the data. There are four measurement scales, nominal, ordinal, interval, and ratio.

How do you measure variables in your research?

One way you can see looking at variables is divide them into quarters Different categories (nominal, ordinal, interval, and ratio). These refer to the measurement levels associated with the variable. In everyday use, the convention is to use the metric level to refer to the kind of variable.

What are variables and how to measure them?

measure variable has a number associated with it. Simply put, a measurement variable (sometimes called a numeric variable) represents some type of measurement and has a number associated with it. For example: 12 cm, 5 feet or 310 meters.

What is a measurable variable?
