Just wondering, can pie charts come up in the higher tier paper? My teacher has never taught us it.
Yup, I remember having to complete one in a past paper, but it was only three marks or so They're not too hard to learn so you may as well, but they hardly ever come up so you might wanna concentrate your revision on something else
Yeah I doubt it will come up again but it did come up once, if they give you values you just have to convert them into degrees really, it came up on a 2011 paper-so due to the exams getting harder i wouldntthink it would come up again
Sorry for being such a doofus, but how do you convert numbers into degrees?
Calculate the total frequency by adding the individual frequencies together, then work out the fraction each one represents e.g. say it was how many cars seen on a road one day Blue - 15 Red - 10 Green - 20 Yellow -27 Total frequency would be 72, then just do each individual one over 72: blue cars would be 15/72 Multiply each fraction by 360 for the number of degrees it represents (15/72 × 360 = 75 degrees) sorry if that wasn't very clear!
Do you think Edexcel are gonna go easy on us considering its the last year ?
They can't make the paper extremely difficult because it tests grade D, C and B stuff as well as the A* stuff. If they make the paper easy though that will mean higher grade boundaries and everyone makes silly mistakes!
