The interquartile range (IQR) is a measure of the dispersion of a dataset. It is calculated as the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of the data and is a way to identify the spread of the middle 50% of the data. In other words, the IQR measures the range

The range is the difference between the largest and smallest values in a group of observations. To calculate the range, you need to find the dataset’s smallest and largest values. Then subtract the smallest value from the largest value. In the case of the numbers 6, 9, 10, 11, 11, and 14, the range would be

 In descriptive statistics, several common variation measurements are used to describe the spread or dispersion of a group of observations. Some of the most common measurements of variation include:Range: The range is the difference between the largest and smallest values in a group of observations. It is a simple and easy-to-understand measure of variation, but it

 Quantiles are an important statistical concept that allows us to divide data into equal groups. They are often used to identify and analyze data patterns and make meaningful comparisons between different datasets. In this quick guide, we’ll cover the basics of quantiles and take a closer look at some of the most common types: quartiles,
