The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!

In math, rangeis a statistical measurement of dispersion, or how much a given data set is stretched out from smallest to largest. In a set of data, the range is the difference between the greatest and smallest value. Range is one of four simple tools of statistics: 1. Mean – The arithmetic mean of a set of numbers is its average (the sum of the num...
To find the range in a set of numbers, you must gather your data, organize the data from least to greatest, then subtract the smallest value from the largest value. You can find a range of positive numbers and negative numbers. Steps for how to calculate range: 1. Gather your data, so you know all the numbers to be studied. 2. Arrange the data set ...
Let's look at some example problems and figure the range. Below are five of the lowest-scoring games in NBA history, listed with teams and total game points: 1. Washington Capitols (49) vs. Pittsburgh Ironmen (40) – 89 points 2. Fort Wayne Pistons (19) vs. Minneapolis Lakers (18) – 37 points 3. Washington Capitols (50) vs. Detroit Falcons (33) – 83...
Range is used in real life to make mathematical calculations. Range can be used to calculate the amount of time that has passed, like when calculating your age. The current year is 2020, and you were born in 2005. How old are you? Or how much time has passed? 15 years have passed, so if your 2020 birthday has already passed, then you are 15 years o...
The definition of range in math can be given as the difference between the maximum value and minimum value within the set. Range is the simplest and quickest way to make sense of the given data points. Example: What is the range of numbers { 23, 27, 40, 18, 25 }? The largest value = 34. The smallest value = 13. Therefore, the range is 34 − 13 = 21.
- What are quartiles in statistics?Quartiles are the points (a set of three points) that divide the data into four equal parts or quarters. The first, second, and third quartile is r...
- What is the interquartile range?The interquartile range (IQR) is the difference between the upper quartile $(Q_3)$ and the lower quartile $(Q_1)$. $IQR = Q_3 \\;−\\; Q_1$
- What is the difference between mean and range?Mean is the average of all the numbers in the given data. It is the best way to analyze the central tendency of the data. It uses all the data poin...
The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of possible outputs.

- If g(x)=x^2/x and x^2/x=x then can we say that: g(x)=x And if we can, how than for x=0 this expressi...When you start with a reciprocal function, you will have at least one vertical asymptote in which the function does not have a value. So by startin...
- OK so I'm totally lost by this. Is this at all like the domain on the function? They seem totally di...The domain of a function is the set of all acceptable input values (X-values). The range of a function is the set of all output values (Y-values)....
- what is the difference between f(x) and y values?f(x) is Y. The equation `f(x) = 2x - 5` is the same a `y = 2x - 5` provided the equation with Y is a function. Not all equation are functions. So,...

- Sorry if this was asked already but what is a non real number and what would an example be?Non-real numbers are called imaginary numbers and are based on i=√-1. You cannot take the square root of negative numbers, so you move to imaginary...

Sep 11, 2020 · Published on September 11, 2020 by Pritha Bhandari . Revised on June 21, 2023. In statistics, the range is the spread of your data from the lowest to the highest value in the distribution. It is a commonly used measure of variability.
The range is the difference between the largest and smallest data points in a set of numerical data. The midrange is the average of the largest and smallest data points. Range is an easy to calculate measure of variability, while midrange is an easy to calculate measure of central tendency.
