Analyzing Math Grades with Quartiles and Percentiles by maritope0404 is a document available to read on EtoBox.
The document provides instructions and calculations for determining various measures of position from a data set of math grades. It shows how to calculate the 1st, 2nd, 3rd quartiles, 7th and 4th deciles, and the 60th and 85th percentiles. The calculations yield the following results: Q1=88, Q2=94, Q3=97, D7=96, D4=91, P60=95, P85=97. These values indicate the grade below which a certain percentage of scores fall (e.g. 25% of scores are at or below a grade of 88).
