If you want to know what score is in the 95th percentile, you would find the range (95-60=35) and divide it by 5 (since there are 5 scores in the set). Range can also be used to find percentiles. This would give you a score that is closer to the real average of the group than if you just took the average of the 60 and 95 scores. For example, if you have a set of test scores that range from 60 to 95, you would take the average of the scores by adding them all up and dividing by the number of scores. Range is often used when working with averages. For example, if you have the numbers 1, 2, 3, 4, 5, the range would be 5-1=4. It is often represented by the symbol “∆”. ![]() However, in set notation, rather than using the symbol "∪," we use the word "or" by convention.Range in math is the difference between the least and greatest value in a set of data. Like interval notation, we can also use unions in set builder notation. Which can be read as "the set of all y such that y is greater than or equal to zero." The range of f(x) = x 2 in set notation is: The above can be read as "the set of all x such that x is an element of the set of all real numbers." In other words, the domain is all real numbers. Using the same example as above, the domain of f(x) = x 2 in set notation is: Standard inequality symbols such as, ≥, and so on are also used in set notation. Indicates that an element is a member of some set "such that" - symbol is followed by a constraint Like interval notation, there are a number of symbols used in set notation, the most common of which are shown in the table below: When using set notation, also referred to as set builder notation, we use inequality symbols to describe the domain and range as a set of values. Note that it is also possible to use multiple union symbols to combine more intervals in the same manner. The domain of the function is therefore all x-values except those in the interval (0, 1), which we can indicate in interval notation using the union symbol as follows: This is the same as our function above, except that it is not defined over the interval (0, 1). In the context of interval notation, it simply means to combine two given intervals. The union symbol can be read as "or" and it is used throughout various fields of mathematics. The union symbol is used when we have a function whose domain or range cannot be described with just a single interval. The range can therefore be written in interval notation as: Recall that the range of f(x) = x 2 is all positive y-values, including 0. We used parentheses rather than brackets around each endpoint because the endpoints are negative and positive infinity, which by definition have no bound. In other words, any value from negative infinity to positive infinity will yield a real result. Recall that the domain of f(x) = x 2 is all real numbers. Let's look at the same example as above, f(x) = x 2 to see how interval notation is used.
