Finding Quartiles Quick and Easy

This method can be used for all types of data sets but is most valuable when you have a large amount of data such as in stem-and-leaf plots.
Also, exam-type questions will generally provide you with the number of data values in the given set, which further contributes to the speed at which you can find the quartiles using this method.

This algorithm assumes that the values are already sorted. Picking quantiles in a sorted stream of arrays is rather easy. Tricky quantiles algorithms are those that don't require sorting (they are actually faster than sorting).

what if you don't get a whole number?

What if your median was 2 numbers and you had to add and divide them leaving you with a decimal ?

this is flipping insane wtfff thank youu

Thank youu so much, its help me doing my group assignment

Here is an even easier way:

If the number of data points is even add 1 and multiply by 1/2 for mean, but if you are trying to find Q1 or Q3, add 2 to the even number of total data and multiply by 1/4(for Q1) or 3/4(for Q3). But if the number of total data are odd, then add 1 for median and quartiles

Can this method use to median, Q1 and Q2 for group data(like in table form)?

[jasperley]

What if the number of data values is an odd???

you magic creature you're majestic

[HanaYuki]

what is the difference between 1/4(n+1) and 1/2(n+1)?

[muddasirkhan]

you're amazing man! appreciate it

[doomsdaycookie]

you explained it well but I have a question, if zero is there do you count that

[Daquarius_.]

is calling q2 the inter-quartile correct?
