Another name for the third quartile of a data set is the 75th percentile. It represents the value below which 75% of the data points fall, indicating the upper range of the data distribution. The third quartile is often denoted as Q3.
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.
Quartile is basically just a quarter, so with cumulative frequency data, you leave out the upper, and lower quartiles because these are the extremeties, leaving you with your correct data
To solve for the quartile deviation, first calculate the first quartile (Q1) and the third quartile (Q3) of your data set. The quartile deviation is then found using the formula: ( \text{Quartile Deviation} = \frac{Q3 - Q1}{2} ). This value represents the spread of the middle 50% of your data, providing a measure of variability.
