Quartiles are the values that divide the given data set into four parts, making three points. The \ (\frac { (n+1)} {4}\) value the upper quartile is the median of the upper half of the data. One quarter, or 25% of the data have values less than or equal to lower quartile.75% of the data values greater than or equal to the lower quartile.

The Formula For Calculating The Upper Quartile Is Q3 = ¾ (N +1).


The \ (\frac { (n+1)} {4}\) value the upper quartile is the median of the upper half of the data. 1 st quartile or lower quartile basically separates the lowest 25% of data from the highest 75%.; So now we have enough data for the box and whisker plot:

The Top Of The Bottom 25 Per Cent Of The Market (The Lower Quartile), And;


3 rd quartile or the upper quartile separates the highest 25% of data from the lowest 75%.; It divides numbers into 2 equal parts. 1 goal 6 six times and 2 goals 3 times.

These Values Are Usually Called The Upper Quartile, Median, And Lower Quartile, And Are Abbreviated As Q 1, Q 2 And Q 3.The Difference Between The Upper And Lower Quartile Is Called The Interquartile Range.


So 53 is our lower quartile. There are 24 values, and you have already ordered them. The quartiles are three values that divide an ordered set of numbers into four equally sized parts.

To Calculate The Upper Quartile, First, Arrange The Numbers Of The Data Set In Ascending Order.


Thus, quartiles are the values that divide the given data into three quarters. Order the data values from smallest to. At q 2 split the ordered data set into two halves.

Lower Quartile (Q 1 ), The Median (Q 2 ), And The Upper Quartile (Q 3 ).


This is the second quartile q 2. Let’s say that we have a data set with n data points: The data set is thus divided into quarters by the.
