How to find quartiles in a data set

What are Quartiles? Quartiles are three values that split your dataset into quarters. These values are the following: Q1 First quartile: 25% of the data are below this value. Q2: Second quartile /

Calculating Quartiles: A Step-by-Step Explanation

In order to find the first and third quartiles, we haave to find the 25th and 75th percentiles, respectively. To find the percentile, we find the product of and the number of items in the set.

Quartile Formula

You can use the following formulas to find the first (Q 1) and third (Q 3) quartiles of a normally distributed dataset:. Q 1 = μ – (.675)σ; Q 3 = μ + (.675)σ; Recall that μ represents
