I think it was frequency. Since everybody or most of us did that frequency density thing so I just don't want everybody to turn against me.
The thing is I checked past papers that redspot thing, I know that's not very reliable but still. One more thing almost in every paper where they ask about f.d they do make atleast two bars already. This is not something hard and fast but this is something I've noticed.

That 2 bars thing is wrong.Look in the ms and er of mj21 paper,no bars given but still we had to make histogram with f.d due to VARYING CLASS WIDTHS

wowowow im so stupid, i didnt shade but added the numbers. :'( how many marks? and the next 2 were related right? shiiitt.

Error carried forward most probably,though the table was of one mark so you'll lose that.

Would we get e.c.f on the mensuration qs. especially the height??
Also if the working is correct but somehow the answer is wrong would we get half the mark if the qs. if of 2-3 marks???

Yes. ECF is applied.
You get 1/3 or 2/3. IMO it would be 2/3 if you did all the steps and only made 1 mistake.

Ask Zain_Rocks. And view them. Just hover mouse over it for a second. That makes it 0. Then start viewing them again (and unwatch threads jin ke you don't want).

MarcoReus ain't no King Joffrey to be able to explain that.

It depends on the class widths given , if they are unequal you just have to make histogram on frequency density otherwise you can make it on frequencies given. In the paper the class widths were unequal, so frequency density had to be used.
