What Does Range Mean In Math Example

There are two ways to define the term range in math.

What does range mean in math example.

The range is the set of all possible output values commonly the variable y or sometimes expressed as f x which result from using a particular function. A graph of a typical line such as the one shown below will extend. In statistics range means the difference between the highest and lowest values in your data set. The single value of 3616 makes the range large but most values are around 10.

There are many useful properties of sets of data that are used in basic mathematical analysis including the range. Additionally the mean or average of the data can be calculated by summing all the numbers and dividing by the amount of numbers in the data. Unlock content over 79 000 lessons. Limitations of range the range is a very crude measurement of the spread of data because it is extremely sensitive to outliers and as a result there are certain limitations to the utility of a true range of a data set to statisticians.

In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6. In 8 11 5 9 7 6 3616. So in our example if the range in the students race times was three minutes that means there was a 3 minute difference between the slowest and fastest runner. 1 3 5 7 9 9 1 8 the range is 8 for this set of data.

The mean is the usual average. The median is the middle number. This is good enough for most students of hi. Range can also mean all the output values of a function.

To get the range in math you take the lowest number in a set of numbers and subtract it from the highest number. In this example the numbers are already listed in numerical order so i don t have to rewrite the list. In other types of math range represents the set of actual outcomes or results that you get after applying a mathematical function. In algebra i like to explain that the range of a function is the set of all possible outputs of that function and the domain is the set of all possible inputs of that function.

The lowest value is 5 and the highest is 3616 so the range is 3616 5 3611. 1 2 4 7 4 14 4 3 5.
