Not sure what to make of this paper, certainly required a little more thought than normal

Q1 - DRV

Easy


Q2 - PMCC

Easy


Q3 - Linear regression

Bit weird but pretty easy


Q4 - Venn

So stupidly easy


Q5 - Measures of location / spread

Very weird - you could have quite easily solved it by spotting that there were 22.5 5x5 squares so each 5x5 square represented 20 cars.

However I think this will be a massive bloodbath with many students picking up no marks.


Q6 - Normal distribution

Harder than normal I would say; I used the % points table to answer b) and c)


Q7 - Probability

Fairly easy but pretty unusual


I am going for

75 - 100ums
68 - 90ums
61 - 80ums
53 - 70ums
45 - 60ums
37 - 50ums
29 - 40ums



This thread will be locked at somepoint and then unlocked at midnight following the Stats 1 examination.

I will upload the paper and my solutions to this post.

I will do my best to answer questions about the paper but please try to read the thread first so that I am not answering the same questions lots of times.

Here are some links to previous S1 threads, they are worth a read and you will see what the common errors were...

The second link contains loads of past papers, model answers etc

Good luck.

First?

This exam was lovely

[yayifications]

I struggled on the histogram question so bad.

[MickyFly42]

:/ ... Fingers crossed!

[Matt_payne]

Unofficial mark scheme!

Good exam other than the histogram question which annoyed me >_<

I revised them all last night, funny feeling there was gonna be a horrible histogram question, as soon as I saw it I'm pretty sure I made a very loud noise in excitement...

[raheem94]

The probability question was really difficult.

[ash-stan]

I thought the exam was nice! desperate to check my answers!

[UWS]

Everything easy apart from the histogram. Lost 9 marks from that

[MickyFly42]

Histogram Q was good! The normal distribution part (c) was a muck-up of a Q... :/

I knew I couldn't do them, I just hoped they wouldn't come up... obviously not a good tactic LOL.

I was stupid enough to draw my tree diagram in pencil, do you think I'll lose marks for it? Other than that it was a decent paper.

[adilh301]

did histogram in last 2 mins made so many stupid slips in the paper

[shorttstuff]

mark scheme! dying to see the histogram question!

[InadequateJusticex]

Anyone else totally mucked up the histogram one? I left the first 3 parts blank, fml

It seems that was the only question that got people - and it got people good! Everything else was good though, yeah.

[miss-medicine]

Some of the probability questions were really tricky!

Easiest paper I've done in my life apart from maybe Unit 2 Chemistry GCSE , only thing i got wrong i think was drawing the regression line on the graph and the skew of the data i got mixed up. :/
