Whats the median of a table that is divided in classes?

Hello ppl, how are you?

So, I got a table with 6 classes like 0 to 6, 6 to 12, 12 to 18... and I have on the other side their absolute frequencies.

How do I find medians of this kind of tables that are divided in classes?

Thanks in advance,

Hey frank1.

Rank the observations in increasing order and get the middle observation and that is your median.

For this particular example you need to find the bin which contains the middle value and then find the average value inside that bin.
