Hence, the formula for quartile can be given by; Where, Qr is the rthquartile l1is the lower limit l2is the upper limit f is the frequency c is the cumulative frequency of the class preceding the quartile class. Quartiles in Statistics ...
As quartiles divide numbers up according to where their position is on the number line, you have to put the numbers in order before you can figure out where the quartiles are. What do quartiles in statistics tell us? If Q1 is further away from the median than Q3 is from the median,...

In statistics, a quartile is a type of quantile which divides the number of data points into four parts, or quarters, of more-or-less equal size. The data must be ordered from smallest to largest to compute quartiles; as such, quartiles are a form of order statistic. Tertile (statistics...
In statistics, quartiles are a method of breaking up a set of numbers into four equal parts. While this concept may seem simple, it actually requires some in-depth calculations to determine the exact numbers that would equally divide the data set, so Excel includes the QUARTILE.EXC function ...
in the example with sas the first quartile is 3, but in excel it is calculated at 3.5, why? data t1; input value; datalines; 1 2 4 7 8 9 10 12 ; PROC MEANS data=t1 q1 ; VAR value; RUN; In excel the result of the following formula is 3.5 instead: =QUARTILE(A2:A9;1) ...
