ratio scale

In this article, you will learn about Ratio Scale.

Researchers can use the Ratio Scale to classify and categorize their data, as well as compare and contrast intervals and differences between data points.

While nominal, ordinal, and interval scales have zero points or origins, the ratio scale has a true zero point or origin of its own. Calculating the scale ratios is easier with a zero point. Weight, age, height, and money are all examples of ratio scales. Sales, market share, price, and the number of customers are all ratio-measured in marketing research.

You can tell how many objects are in a given range of values. Researchers can use any statistical technique, such as geometric mean, harmonic mean, and coefficient of variation, with the ratio scales at their disposal. A statistical tool, such as the mean, median, or mode, can be used to determine the central tendency.

Only the proportionate transformation of the form y = bx, where b is a positive constant, can be achieved using ratio scales. As in the interval scale, an arbitrary constant cannot be added to it. The example of converting a centimeter to a millimeter (b = 10) can be used to demonstrate this transformation. When comparing objects in centimeters or millimeters, it is important to note that the comparison is the same.
