agsfaltex,

Can you please explain how you got median as 3 @ 40% of the project when combining 1 and 2.

Is it becos of the 4 or more and 2 or fewer key words...?

C it is...

35% <=2 25% >=4
---------------|------------------|------------

Hence middle 40% has to be 3 (employees cannot be fractions)

Its not only because the key words say thet a fraction is 4 or over and 2 or under, but because the fraction of 3 (40%) is the larger fraction of the three, making it the fraction of the whole that has the median in it.

Nicely put. To add to this, one must be careful to ensure that the median is actually the middle value in the case of an odd number of elements, or the average of the 2 "middle" elements in case the number is even. For example if 40% of the values are 3, 20% are 4, and 40% are 5, the median is 4, even though its not the largest fraction of the three.
