Answer:
Explanation:
The advantages of a ratio scale over an interval scale.
1. Because a ratio scale of measurement has an absolute zero rather than an arbitrary origin, it is seen to be the most potent of the four measurement scales. It includes all the characteristics of the other three measuring scales as a result.
2. Because ratio units are immediately comparable and all have the same value, ratio scale data are more useful than ordinal and nominal data.
3. A ratio scale variable may be used with any statistical method since it has an absolute zero point. Businesses utilise ratio scales to measure revenue, expenses, market share, and the number of clients for this reason.
4. Since ratio data is measured using a continuous, equidistant scale that displays order, direction, and an exact difference in the ratio units, calculations based on ratio data are precise.
5. Ratio data can be utilised in situations where negative values are prohibited because they have a "true zero," which represents the lack of the variable. For instance, stature, weight, yearly income, sales, and more.
6. Because ratio data lacks negative values, it may be added, subtracted, multiplied, and divided unlike the other three categories of data.
7. You can compute statistical measures like the mode, median, and mean as well as range, standard deviation, variance, and coefficient of variation using ratio scale data.

Answer:
Concept:
Any range of numbers with a calculable difference but no actual zero is an interval scale.
Explanation:
These include common measuring units with fixed interval variables (degrees), such as Fahrenheit and Celsius, but arbitrary zero values. Absolute zero, the lowest temperature that is conceivable theoretically, is not, for instance, zero degrees on either temperature scale.
Interval scales differ from ratio scales, such as Kelvin, in that they lack an absolute zero value. Because absolute values are simpler to manipulate than relative ones, ratio scales are more useful in mathematics. Because they allow you to give numerical values to arbitrary measurements, like an opinion, interval scales can be helpful in statistics on occasion.
An interval scale is distinct from an ordinal scale, which consists of relative values with no discernible mathematical difference, despite the fact that both can quantify perception or opinion. You are employing an ordinal scale when you inquire as to whether the weather is hot, warm, or chilly. You are utilizing an interval scale when you inquire as to the current temperature.
