18 paź 2024 · The five-number summary is a collection of five key values that summarize the important characteristics of a data set: Minimum: The smallest number in the data set. First Quartile (Q1): A value representing the point where the lowest 25% of the data lies. Median (Q2): The middle value, splitting the data into two halves.
The Interquartile Range (IQR) is the distance between the third and first quartile and it is an integral part of the 5 number summary. This range indicates where the middle 50% of the data fall. Conversely, you also know that 50% falls outside this range, 25% above and 25% below the IQR. Like the range, the IQR is also a measure of variability.
