What is used in a five-number summary of a data set?
One possibility is minimum, lower quartile, median, upper quartile and maximum.
What is the average value of a data set?
What is a visual Representation of the five number summary minimum first quartile medium third quartile and maximum
Howdoes the term quartile relate to how data values are grouped when using a five number summary?
Each quartile contains 25% or one quarter of the total.A quartile and a quarter are not the same thing.
What is the semi quartile range?
The semiquartile range is half the difference between the quartiles. So find Q3 and subtract Q1 then divide that number by 2.
How do you find the inter-quartile of 7 numbers?
The interquartile range is the difference between the Lower quartile and the upper quartile. Obviously you need to be able to find these values. Haylock (2006) explains how to do this for difficult size groups in mathematics explained for primary teachers. He explains the position of the lower quartile is a quarter of (n+1) and that of the upper quartile is three-quarters of (n+1). So for a group of 7 numbers, you find a quarter of 8, which is 2. Therefore the number in second place is the lower quartile. Three quarters of 8 is 6 and so the number in 6th position is the upper quartile. Now take the lower quartile from the upper quartile.
What is the name for the difference between the first quartile and the third quartile in a five number summary?
75th percentile
What is the name for the difference between the third quartile and first quartile in a five number summary?
interquartile range or IQR
What is a five number summary?

What is the difference between minimum and lower quartile?
Consider the data: 1, 2, 2, 3, 4, 4, 5, 7, 11, 13 , 19 (arranged in ascending order) Minimum: 1 Maximum: 19 Range = Maximum - Minimum = 19 - 1 = 18 Median = 4 (the middle value) 1st Quartile/Lower Quartile = 2 (the middle/median of the data below the median which is 4) 3rd Quartile/Upper Quartile = 11 (the middle/median of the data above the median which is 4) InterQuartile Range (IQR) = 3rd Quartile - 1st Quartile = 11 - 2 = 9
What are a set of numbers representing some sort of information from the sample population?
One example is the "Five Number Summary" consisting of the sample's minimum, lower quartile, median, upper quartile and maximum.
What is the five number summary of a set of numbers?
The five number summary consists of the Minimum, the Lower Quartile, the Median, the Upper Quartile, and the Maximum.For Example, if you have a number set like this:2, 3, 5, 7, 9, 12, 15, 15, 18, 19, 21,Minimum: 2Q1: 5Median: 12Q3: 18Maximum: 21
