The quartiles for a set of data are three values - the lower quartile, the median and the upper quartile - such that they divide the data set into four parts with an [approximately] equal number of observations in each. Thus:
- a quarter of all the observations are smaller than the lower quartile,
- a quarter of all the observations are between the lower quartile and the median,
- a quarter of all the observations are between the median and the upper quartile, and
- a quarter of all the observations are greater than the upper quartile.

What else can I help you with?
Are the upper and lower quartiles classed as averages?
No.
How do you use quartiles in real life?
Quartiles are used in real life to analyze data distributions and make informed decisions. For example, in education, they can help assess student performance by categorizing test scores into quartiles, allowing educators to identify students who may need additional support. In finance, quartiles can be used to evaluate investment performance, helping investors understand how a particular asset compares to others in the market. Overall, quartiles provide valuable insights into data trends and help identify outliers.
Are quartiles divided into four equal quarters?
Yes it does.
What are quartiles in relationship to mean median mode?
Quartiles are values that divide a sample of data into four groups containing the same number of observations. You will find details in the related link.
What does the distance between the quartiles tell you?
It gives you the interquartile range
How many quartiles are there?
There are 5 quartiles in any data set.
What does IQR mean in math?
The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts.
How do you find the first and third quartiles?
37
Are the upper and lower quartiles classed as averages?
No.
How do you find the inner and outer quartiles?
To find the inner quartiles (Q1 and Q3), first arrange your data in ascending order. Q1 is the median of the lower half of the data, and Q3 is the median of the upper half. The inner quartiles divide the data into four equal parts. The outer quartiles also known as the minimum and maximum values, are the smallest and largest values in the data set.

What is the interquartile range a measure of?
The interquartile range is well known as a measure of statistical dispersion. It is equal to difference between upper and lower quartiles. The quartiles is a type of quantile.
What is quartiles?
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.

Is quartiles another way to describe the dispersion of a distribution?
Yes, quartiles are a statistical measure that can describe the dispersion of a distribution. They divide a dataset into four equal parts, providing insights into the spread and variability of the data. Specifically, the interquartile range (IQR), which is the difference between the first and third quartiles, quantifies the range within which the central 50% of the data lies, highlighting how spread out the values are. Thus, quartiles are useful for understanding both central tendency and dispersion.
