Stated succinctly we have the following formula: Range = Maximum Value–Minimum Value. For example, the data set 4,6,10, 15, 18 has a maximum of 18, a minimum of 4 and a range of 18-4 = 14.

What is the formula to find the range?
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!
What is the range in math?
The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
What are the formula and steps in solving for the range?
R = H – L
- R is the range.
- H is the highest value.
- L is the lowest value.
How do you write a range?
The correct treatment of a range numbers expressed in numerals is one number followed by an en dash (although some publications employ a hyphen) and another number, with no letter spaces: “The school enrolls students in grades 9–12.”
How do you calculate range of marks?
To find the range, first put all the numbers in order. Then subtract (take away) the lowest number from the highest. The answer gives you the range of the list.
What is range on a graph?
Definition of the domain and range
The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function. When looking at a graph, the domain is all the values of the graph from left to right. The range is all the values of the graph from down to up.
How do you find the range and interquartile range?
Steps:
- Step 1: Put the numbers in order.
- Step 2: Find the median.
- Step 3: Place parentheses around the numbers above and below the median. Not necessary statistically, but it makes Q1 and Q3 easier to spot.
- Step 4: Find Q1 and Q3.
- Step 5: Subtract Q1 from Q3 to find the interquartile range.
How do you find the range in math graph?
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
How do you find the range of a bar graph?
Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find it, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
What is the range of a function example?
The set of all output values of a function. Example: when the function f(x) = x2 is given the values x = {1,2,3,…} then the range is {1,4,9,…}
What is Iqr in math?
The “Interquartile Range” is the difference between smallest value and the largest value of the middle 50% of a set of data.
What is the range on a box plot?
Range. If you are interested in the spread of all the data, it is represented on a boxplot by the horizontal distance between the smallest value and the largest value, including any outliers.
How do you find the interquartile range example?
Q3 is the middle value in the second half of the data set. Again, since the second half of the data set has an even number of observations, the middle value is the average of the two middle values; that is, Q3 = (6 + 7)/2 or Q3 = 6.5. The interquartile range is Q3 minus Q1, so IQR = 6.5 – 3.5 = 3.
What is domain and range example?
Consider the relation {(0,7),(0,8),(1,7),(1,8),(1,9),(2,10)} . Here, the relation is given as a set of ordered pairs. The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} .
