Quartile 1 (Q1) = 4; Quartile 2 (Q2), which is also the Median, = 5; Quartile 3 (Q3) = 7

2022年5月20日 · Quartiles are three values that split sorted data into four parts, each with an equal number of observations. Quartiles are a type of quantile. First quartile: Also known as Q1, or the lower quartile. This is the number halfway between the lowest number and the middle number. Second quartile: Also known as Q2, or the median.

2023年9月19日 · This quartile calculator and interquartile range calculator finds first quartile Q 1, second quartile Q 2 and third quartile Q 3 of a data set. It also finds median, minimum, maximum, and interquartile range. Enter data separated by commas or spaces. You can also copy and paste lines of data from spreadsheets or text documents.

We sort a set of data with n items (numbers) and pick the n/4th item as Q1, the n/2th item as Q2, and the 3n/4th item as Q3 quartile. If indexes n/4, n/2, or 3n/4 aren't integers, then we use interpolation between the nearest items.

Using the quartile formula we can find the first quartile, second quartile, and third quartile. What Is Quartile Formula? The quartile formula helps to divide a set of observations into 4 equal parts. The first quartile lies in the middle of the first term and the median. The median is …

First Quartile is denoted by Q 1 known as the lower quartile, the second Quartile is denoted by Q 2 and the third Quartile is denoted by Q 3 known as the upper quartile. Therefore, the interquartile range is equal to the upper quartile minus lower quartile. The difference between the upper and lower quartile is known as the interquartile range.

The lower quartile, Q1, is the median of the lower half of the data (from the first element to Q2). The upper quartile, Q3, is the median of the upper half of the data (from Q2 to the final element). The following formulas can be used to determine the position of each quartile.
