Roughly speaking, finding the third quartile is similar to finding the median. First, use the median to split the data set into two equal halves. Then the third quartile is the median of the upper half. Similarly, the first quartile is the median of the lower half.
The median is the middle value in a dataset when it is sorted in ascending order. It divides the data into two equal parts. Quartiles, on the other hand, divide a dataset into four equal parts. The first quartile (Q1) is the median of the lower half of the data, the second quartile (Q2) is the median of the entire dataset (same as the median), and the third quartile (Q3) is the median of the upper half of the data.
the IQR is the third quartile minus the first quartile.
To find the upper quartile (Q3) of the dataset, first, arrange the numbers in ascending order, which they already are. The upper quartile is the median of the upper half of the data. In this case, the upper half consists of the numbers 110, 115, 120, 125, 130, 135. The median of these values is the average of the third and fourth numbers (120 and 125), which is (120 + 125) / 2 = 122.5. Thus, the upper quartile is 122.5.
The data is divided into four equal parts by quartiles. The first quartile (Q1) marks the 25th percentile, the second quartile (Q2) is the median or 50th percentile, and the third quartile (Q3) represents the 75th percentile. These quartiles help to understand the distribution of the data by segmenting it into four intervals, each containing approximately 25% of the observations.
Roughly speaking, finding the third quartile is similar to finding the median. First, use the median to split the data set into two equal halves. Then the third quartile is the median of the upper half. Similarly, the first quartile is the median of the lower half.
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.
The first quartile, or the lower quartile, is the value such that a quarter of the observations are smaller and three quarters are larger.The third quartile, or the upper quartile, is the value such that three quarters of the observations are smaller and a quarter are larger.

It is the outlier.
Graphing to determine difference between third and first quartile as well as to find the median between the two. Also known as semi-interquartile range.
A quartile divides a distribution into four equal parts, each containing 25% of the data. The first quartile (Q1) represents the value below which 25% of the data fall, the second quartile (Q2) is the median, and the third quartile (Q3) is the value below which 75% of the data fall.
the IQR is the third quartile minus the first quartile.
