By using the basic definition of a quartile. Sort the data, count how many there are in total, then count off one quarter of that. For example, if you have 80 data items, count off the first 20 items (after sorting).

How do you calculate the range of data?
You take the largest number in the Set of data and then subtract it from the smallest number in that data
How do you get the lower class boundary of the median?
The median is the middle number in a data set. The lower class boundary is the first quartile or number that is 25 percent lowest in the data set.
What is a data value that is much lower or higher than the other data in a set?
It may be an outlier.
How can you describe a set of data in a spreadsheet?
A set of data can be described to the spreadsheet as a range by specifying the beginning cell, in the upper left corner of the data, and the ending cell, in the lower right corner of the data.
How do you find the Quartile of a number?
A number does not have a quartile, a set of data does. The lower quartile of a set of data set is a value, in the data set, such that a quarter of the date set are smaller and three quarters are larger. The upper quartile is defined similarly. The middle quartile, better known as the median, divides the data set in two.
What is a lower quartile?
A lower quartile i s the mediaon of the lower half of a data set. A data set is divided up into different quartiles.
What is it called when you calculate by subtracting the smallest value in the data set from the largest value in the data set?
The range.
What is the median of the lower half of a data set called?
It is the lower quartile.
How do you calculate the range of data?

How do you calculate numbers in a math data set?
To calculate the cardinality of a set you need to establish a 1-to-1 mapping from the set onto Z, the set of counting numbers.
How do you calculate the first and third quartiles on a Casio fx-115 es?
The Casio fx-115 ES is a scientific calculator which you can use to calculate the first and third quartiles of a data set. To calculate the first and third quartiles, you first need to arrange the data set in ascending or descending order. Once the data set is arranged, you can use the following steps to calculate the first and third quartiles: Enter the data set into the calculator by pressing the Data/Matrix button. Once the data set is entered, press the STAT button and then the VARS button. Select the data set by pressing the number key that corresponds to the data set. Access the QUARTILE option by pressing the 5 key. Enter the number 1 to calculate the first quartile or enter the number 3 to calculate the third quartile. The calculator will display the first or third quartile of the data set. These steps can be used to calculate the first and third quartiles on a Casio fx-115 ES.

The median is the middle number in a data set. The lower class boundary is the first quartile or number that is 25 percent lowest in the data set.
What are the upper and lower quartiles of the data set?
The upper quartile is the value such that a quarter of the data are greater than that value. Similarly, the lower quartile is the value such that a quarter of the data are lower than that value.
What is a data value that is much lower or higher than the other data in a set?
It may be an outlier.
