Statistics GCSE 2016

Yup. if the it would be like 1,2,3.5,3.5,5,6

So can you give a model answer

how did you find it and what did you get?

If you are doing A level Maths (or already are) you should be doing it anyway.

Ok before I go can I just verify for the last time two advantages of a questionnaire are
It's cheaper to do
A questionnaire is a faster way to collect lots of data
Am I right guys?👍

Doubt that would occur. You know what happens if two values are the same right?

No because it has to be an advantage in comparison to something. So for example face-to-face interviews in comparison to questionnaires. You'd use questionnaires in this instance as they are less time consuming(faster) and cheaper yes.

When you have 2 values do you add together and divide by two ?! Is that right ?

Indeed. You say quicker and cheaper but compared to what?
You can just say quick way and cheap if you're not directly contrasting I guess.

Honestly I think it's quite an easy GCSE, I got an A in the end.

Actually I'm in year 11( like you?) and finished my exams on the 17th xD. How about you, are you doing A level maths? And how do you find it?

Yup. if the it would be like 1,2,3.5,3.5,5,6

No. So say you have 5 values.

1,3,5,5,8

The numbers '5' are competing for the 3rd and 4th value. So 3+4/2. So you don't add the 2 values but the position they are in.

You know when you have outliers after you've found out 1.5 times IQR and all that ... How do you know which one is the outlier ?

So the rank for 5 is 3.5

Nope, im in year 10. This is my first important GCSE.

What? I am just saying the advantages not in comparison just the advantages
