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.

How do you find the inter-quartile of 7 numbers?
The interquartile range is the difference between the Lower quartile and the upper quartile. Obviously you need to be able to find these values. Haylock (2006) explains how to do this for difficult size groups in mathematics explained for primary teachers. He explains the position of the lower quartile is a quarter of (n+1) and that of the upper quartile is three-quarters of (n+1). So for a group of 7 numbers, you find a quarter of 8, which is 2. Therefore the number in second place is the lower quartile. Three quarters of 8 is 6 and so the number in 6th position is the upper quartile. Now take the lower quartile from the upper quartile.

What is middle quartile?
The middle quartile, also known as the second quartile or the median, is the value that divides a data set into two equal halves. It represents the 50th percentile, meaning that 50% of the data points are below this value and 50% are above it. To find the middle quartile, you can arrange the data in ascending order and identify the middle number, or the average of the two middle numbers if the data set has an even number of observations.

How do you calculate the third quartile for a mean of 110 and a standard deviation of 15?
If this is the only information you have, the answer would be somewhere around 125. Usually, you would find the third quartile by first finding the median. Then find the median of all of the numbers between the median and the largest number, which is the third quartile.

How do you find the IQR of a set of data?
Iqr stands for inter quartile range and it is used to find the middle of the quartiles in a set of data. To find this, you find the lower quartile range and the upper quartile range, and divide them both together.
How do you find upper quartile?
you look on your y axis the one that's horizontal and get 75% of that number and go along that number on your graph till it reaches your line of best fit then go down. anything above that line is your upper quartile

What is a quartile in a math problem?
A quartile is a given section in a range of data. To find the quartile, you must first find the median. Then find the "median of the median", using these to separate your data into sections, giving you a total of four sections of data.
