if we know that 25 percent have 4 or more, we know that the median is a whole number less than four.
if we know that 35 percent have two or less we know that the median is a whole number greater than 2.
Put them together the only whole number that exists is 3...
I am still not getting this. Median simply means the middle number of the set right? i.e middle number if number of terms is odd, average of the two middle numbers if the number of terms is even.
Lets assume there are 100 projects in the company. So (1) says 25 projects have 4 or more people and (2) says 35 projects have 2 or more people. But this is still not giving us any info about the (100 - (25 + 35)) = 40 other projects. How do you know how many people they have? Also, how do you know which numbers are in the middle of the set?
