S1 Edexcel Jan 2013 Post Exam Thread (Model answers in first post) Watch
Q1. Standard correlation. I think the mark scheme will be very generous in part c)
Q2. DRV. Pretty easy if you revised cumulative distribution questions.
Q3. Regression. Fairly easy as it was obvious that t was x.
Q4. Normal distribution. Standard apart from c) I think that will cause a lot of problems.
I think part c) is very badly worded.
Q5. Measures of location/spread. Standard. The histogram part is very easy but always causes problems. Finding the probability using normal distribution is not going to be necessary.
Q6. DRV/Probability. Quite a confusing question, I think this will cause quite a few problems.
Q7. Venn. I thought this was pretty easy but I can see it causing a lot of problems.
