What are the Give essential features of ratio?
Answers
Explanation:
characteristics of ratio data
1. absolute point zero - Ratuo data is measured ona ratio scale
2. no negative numerical value - ratio data
doesn't have any negative numerical value.
3. calculation -ratio data values can be added, subtracted, divided and multiplied
Ratio Data is defined as quantitative data, having the same properties as interval data, with an equal and definitive ratio between each data and absolute “zero” being treated as a point of origin. In other words, there can be no negative numerical value in ratio data.
Characteristics of Ratio Data
1. Absolute Point Zero – Ratio data is measured on a ratio scale. One of the distinctive characteristics of ratio data is the true absolute zero point, which makes the data relevant and meaningful in a manner where it is right to say, “one object is twice as long as the other” or 4 has twice the value as 2.
2. No Negative Numerical Value – Ratio data doesn’t have any negative numerical value. For a value to be a ratio data researcher, first must evaluate if it meets all the criteria of interval data and has an absolute zero point. For example, weight cannot be negative, -20 Kgs doesn’t exist.
3. Calculation – Ratio data values can be added, subtracted, divided, and multiplied. A unique statistical analysis is possible for ratio data. Chi-square can be calculated using a ratio scale for ratio data. Mean, mode and median can also be calculated for the ratio data.
