Would anyone be able to tell me what the following questions were:
7, 16, 18, 23
I remember that the question 23 was on the histogram if thats any help
2. (Original post by console.log)
Did it ask you to convert from CM to M for the part C? If so, I may have done it wrong ;(
Not sure, but I didn't.
And the answer here is in cm.

Hopefully it's cm!

Edexcel overrates working out percentage / percentage increase, so it was 3 marks.
3. Hi i made a small calculation error on the last question and got 81 instead of 80.4, i was wondering how many of the 6 marks ill get on it?

7 was the trial and improvement question, 16 was the cumulative frequency one where you had to get the median and IQR, do you know what 10, 21 and 23 was?
5. There's a full solutions video out on YouTube (I can't post the link here). Its under the name: Maths Paper 2 June 2016 FULL SOLUTIONS MARK SCHEME and by iDeviceJ

Question 16 was cumulative frequency, 1 mark for median and 2 for IQR (so 3 in total)

it was easy you surely didn't skip it!

16 was on the cumulative frequency then you work out the median and the inter-quartile range from the graph... I think?!

**** what are the marks for each question?
18. Could you put the marks next to each question
19. (Original post by hannah2578)
i got 9.25
It was 9.25
20. Trial and improvement answer was different for different methods. Working out 3.75 would give you the answer 3.8. But doing it this way:

3.7 = 34 - 32.153 = 1.847 (the amount 3.7 is lower than x)
3.8 = 35.872 - 34 = 1.872 (the amount 3.8 is above x)

Would give you answer 3.7. I don't know what they will accept as the correct answer.
