Who do you work out the upper and lower quartile?
you do work out the upper and lower quartile
How do you solve a third quartile?
Roughly speaking, finding the third quartile is similar to finding the median. First, use the median to split the data set into two equal halves. Then the third quartile is the median of the upper half. Similarly, the first quartile is the median of the lower half.
How do you find the inter quartile range?
Subtract the lower quartile from the upper quartile.
What is the Definition of lower quartile?
in a set as such {2,3,4,5,6,7,8,}, 5 would be the median, 7 would be the upper quartile, and 3 would be the lower quartile. The lower quartile divides the lower half of a set of data into two equal parts
Inter quartile range?
the interquartile is just subtracting the high quartile from the low quartile. * * * * * No, it is subtracting the lower quartile from the higher quartile.
What are characteristics of lower quartile?
25% of the observed values are smaller than the lower quartile.
How do you finde iqr?
IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.
Can interquartile range be used for any data eg data below the lower quartile to find if the data is spread out or close together or must we use the lower quartile for data below the lower quartile?
No, interquartile range cannot be for any data. The lower quartile for data must be used below the lower quartile.
Formula calculating lower quartile?
lower quartile = 1/4(n+1) upper quartile = 3/4(n+1) where n is the number of the values. Obviously the values have to be ordered from the lower to the higher: the number you'll get is the position in this order. Let's say you get 4 for your lower quartile, it means that the 4th value is your lower quartile.
What is the interquartile range equal to?
It is the upper quartile minus the lower quartile.
What is the lower quartile of 45 47 50 and 51?
A lower quartile for a set of four observations is not a meaningful concept.
What is a lower quartile?
A lower quartile i s the mediaon of the lower half of a data set. A data set is divided up into different quartiles.
