  • This is great but in my class I am studying how to find the median value of a freq. chart, not just what interval it is in? We`re using the equation L + (i/f x C). Do you have any videos on that?

  • did he say a mcdonalds party? ahah

  • thanks! this helped so much!

  • @pr3datordr0n3psn no one cares that u dont care either ^_^

  • Hi. I have a question about calculating mode in interval data. On the example you presented it's clear that the interval 20<x<25 has the highest frequency, but doest it always mean than it's the modal class? What if the highest frequency of most common number within this class is 3 while in the first class (10<X<15) is 5? Can we really determine which one is the modal class? It's just not clear for me. Could you please explain? I would appreciate :-)

  • no1 cares if your 14

  • @jasonvorhees24 now simon pegg i agree with. that guy that says he sound like Karl Pilkington is full of shit

  • @bennye19 firstly he sounds nothing like Karl Pilkington. secondly Karl Pilkington sounds AWESOME.
