What does range mean in math example.

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. In 8 11 5 9 7 6 3616. To get the range in math you take the lowest number in a set of numbers and subtract it from the highest number. In 4 6 9 3 7 the lowest value is 3 and the highest is 9 so the range is 9 3 6.

The range of a simple linear function is almost always going to be all real numbers. The median is the middle number. 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. The single value of 3616 makes the range large but most values are around 10.

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. In this example the numbers are already listed in numerical order so i don t have to rewrite the list. The lowest value is 5 and the highest is 3616 so the range is 3616 5 3611. Range can also mean all the output values of a function.

In statistics range means the difference between the highest and lowest values in your data set. 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. In other types of math range represents the set of actual outcomes or results that you get after applying a mathematical function. There are two ways to define the term range in math.

1 3 5 7 9 9 1 8 the range is 8 for this set of data. That depends on context. 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. 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.

There are many useful properties of sets of data that are used in basic mathematical analysis including the range. The mean is the usual average.
