"Quartiles" Meaning
In statistics, the quartiles are values that divide a data set into four equal parts, or quarters, containing approximately 25% of the data in each part. The three quartiles are:
1. First quartile (Q1): The value below which 25% of the data falls.
2. Second quartile (Q2): The value below which 50% of the data falls, and the median of the data set.
3. Third quartile (Q3): The value below which 75% of the data falls.
Quartiles are often used to summarize a data set and can provide a rough idea of the distribution of data.

Quartiles Usage Examples
1. Statistical Context
The analyst divided the dataset into quartiles to understand the distribution of scores among students. The first quartile (Q1) was 70, which represented the lowest 25% of scores, while the third quartile (Q3) was 85, indicating the top 25%.2. Numerical Example
To calculate the quartiles, we need to arrange the numbers in ascending order: 20, 25, 30, 40, 55, 67, 75. The first quartile (Q1) is the middle value of the lower half, which is 30. The second quartile (Q2), or the median, is 40. The third quartile (Q3) is the middle value of the upper half, which is 55.3. Finance
Quartile deviations can be used as a risk-measurement tool in finance. For instance, a portfolio manager can use lower and upper quartiles (Q1 and Q3) to determine the volatility range.4. Descriptive Statistics
In descriptive statistics, quartiles are used to summarize data distributions. Quartile differences (IQR) between Q3 and Q1 are used as an indicator of data spread, ignoring outliers.5. Business Analysis
In business, quartiles help risk managers understand how data is spread and help in identifying important fluctuations in the data. For example, customer satisfaction levels vary across quartiles, from lowest (scores 0-2) to highest (scores 5-7)."Quartiles" Similar Words
