February 3, 2020 - Instructions: This quartile calculator will calculate a quartile you specify, showing step-by-step calculations, for a sample data set you specify in the form below: The k-th quartile (first, second or third quartile) of a distribution corresponds to a point with the property that 25% of the distribution is to the left of the first quartile (\(Q_1\)), 50% of the distribution is to the left of the second quartile (\(Q_2\)) and 75% of the distribution is to the left of the third quartile (\(Q_3\))

Since quartiles are basically medians of different parts of the data, they can be calculated using the median formula. Alternatively, you can use the formula above. Below you will find an example of both methods. ... Step 1: Find the median.

For the given set of data, the calculator will find the upper (third) quartile (75th percentile), with steps shown.

This value splits your data into two equal halves, with 50% of the data points lying below Q2. ... The third quartile, or Q3, is the value at the 75th percentile of your data. This indicates that 75% of your data points fall below Q3. To find Q3, locate the median of the upper half of your data set. Example 1: Suppose you have the following data set: 15, 22, 29, 34, 37, 40, 45, 50. To find the quartiles: ... Our Quartiles Calculator automates these steps, ensuring you receive accurate results without having to perform each calculation manually.

This statistics calculator will calculate the first quartile (Q1), second quartile (Q2) or the median, third quartile (Q3), minimum value, and maximum value of the given data set.

October 6, 2025 - Spiegel M.R., Stephens L.J. Schaum's Outline of Statistics; McGraw-Hill Education; 2018 ... Welcome to the quartile calculator, where we'll learn how to calculate quartiles of a dataset. In fact, whenever we have a collection of numbers that we want to understand better using statistics, finding the quartiles is one of the first things that comes to mind. Therefore, we will study the topic slowly and in depth. We'll begin with the quartile definition and quartile formulas, and then jump straight to the problem of how to find Q1 and Q3, where Q1 denotes the first quartile (sometimes called the lower quartile), and Q3 is the third quartile (or upper quartile, if you please).

The online calculator computes the first (lower), second (median), and third (upper) quartiles from a set of numerical data. These quartiles are equal to the 25th, 50th, and 75th percentile.

For the following set of data, calculate all quartiles and interquartile range. ... Step 1: Arrange the data into ascending order.

November 4, 2025 - Calculator online for descriptive or summary statistics including minimum, maximum, range, sum, size, mean, median, mode, standard deviation, variance, midrange, quartiles, interquartile range, outliers, sum of squares, mean deviation, absolute deviation, root mean square, standard error of ...

So, to find the first quartile, we need to place the numbers in value order and find the bottom half. Note: 1) If the given data set has even numbers, Find the median from the bottom half · 2) If the given data set has odd numbers, Find the median or average from the bottom half · Want to find complex math solutions within seconds? Use our free online calculator to solve challenging questions. With Cuemath, find solutions in simple and easy steps.

May 18, 2021 - The commas are optional; you can just separate each number with a space if you like. If you don’t enter commas, the calculator will put the commas in for you. Step 2: Press the “Find the Interquartile Range!” button. Step 3: Scroll down to find the solution. The calculator will give you the interquartile range (which for this particular set of data is 9) and it also returns the 1st quartile (25th percentile), 2nd quartile (50th percentile — the median) and the third quartile (75th percentile).

Quartiles Calculator - find the 25th percentile, 50th percentile, and 75th percentile values.

Free upper quartile (third quartile) Calculator - find the Upper Quartile (Third Quartile) of a data set step-by-step

For the given set of data, the calculator will find the lower (first) quartile (25th percentile), with steps shown.

This quartile calculator finds the first quartile (lower), second quartile (median) and third quartile (upper) of a data set and is designed for helping in statistics calculations.

Our quartile calculator finds the first quartile(Q1), second quartile(Q2), third quartile(Q3) and Interquartile Range (IQR) of given set of numbers.

November 8, 2022 - Quartile Calculator calculates the three main quartiles of a set of numbers. Enter the set of numbers in the input field of the calculator and choose the method to be used to calculate quartiles.
