Colleges report GPA (grade point average) on a 4.0 scale. The top grade is an A, which equals 4.0. You calculate your overall GPA by averaging the scores of all your classes. This is the standard scale at most colleges, and many high schools use it.
A qualitative or categorical variable is a variable that does not have a numeric value but is classified into categories. For example, the variable " the number of children" is discrete and the variable " GPA" is continuous. Since GPA can take an infinite number of possible values, for example interval 0.0 to 4.0.
1. Mathematically or statistically, there is a problem with the concept of a Grade Point Average. In a technical sense, letter grades are Ordinal (rather than Interval) numbers — meaning, the distance between two letter grades is not the same.
An interval scale can be defined as a quantitative measurement scale where variables have an order, the difference between two variables is equal, and the presence of zero is arbitrary. It can be used to measure variables that exist along a common scale in equal intervals.
Interval data always appears in the form of numbers or numerical values where the distance between the two points is standardized and equal. A simple example of interval data: The difference between 100 degrees Fahrenheit and 90 degrees Fahrenheit is the same as 60 degrees Fahrenheit and 70 degrees Fahrenheit.
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.
Return policies are the rules a retailer creates to manage how customers return and exchange unwanted merchandise they purchased. A return policy tells customers what items can be returned and for what reasons, and the timeframe over which returns are accepted.
