A quartile is a statistical term that describes a division of observations into four defined intervals based on the values of the data and how they compare to the entire set of observations. Quartiles are organized into lower quartiles, median quartiles, and upper quartiles. When the data poi...
Refer to the box plot below to answer the question: What is the interquartile range for this data set? Compute the interquartile range for the following data: 10, 15, 17, 21, 25, 12, 16, 11, 13, 22. Calculate Interq...
It is a measure of the spread of the variable. Also, in conjunction with the median, it gives a measure of the skewness. Wiki User ∙12yago This answer is: Add your answer: Earn +20pts Q:What does the upper quartile and lower quartile show in a box and whisk...
The interquartile range is obtained by subtracting the first quartile from the third quartile: Q3 – Q1. It represents the range of the middle half of the data, providing insights into the overall spread of data. How to calculate quartiles in statistics Order the numbers: 2, 5, 6, 7, ...
When you're given a set of numbers, what kind of metrics or measurements can you use to learn more about the data set? One simple yet important idea is breaking the set intoquartilesor roughly breaking it into fourths and examining what the breakdown tells us about the numbers in the set...
The line inside the box represents the median (Q2; the 50th percentile) of the data. The box’s right edge or top end represents the third/upper quartile (Q3; the 75th percentile) of the data. If a dot, cross or diamond symbol is present inside the box, this represents the mean of...
The interquartilerangeis calculated as Upper Quartile – Lower Quartile. Examples Using Quartile Formula Example 1:Calculate the median, lower quartile, upper quartile, and interquartile range of the following data set of values: 20, 19, 21, 22, 23, 24, 25, 27, 26 ...
What is a Box Plot? A Box Plot is the visual representation of the statistical five number summary of a given data set. A Five Number Summary includes: Minimum First Quartile Median (Second Quartile) Third Quartile Maximum Mathematician John Tukey first introduced the “Box and Whisker Plot” ...

(or what value a set of data can be 'found around'). Standard deviation and interquartile range are also useful to indicate the distribution of the data around these means and medians, but range provides additional crucial information about the overall spread of data and possible influences ...
