AQA S1 , No working out needed ?

Yes. Most questions have several method marks that you'd miss if you were to skip to the answers immediately.

Based on the past papers I have done (only a few) you don't need to show working out for most things?
For example product moment correlation coefficient doesn't require any working out.
If you get the right answer then you get all the marks.

I'd suggest looking through past papers and look at the mark schemes. I'm not quite sure.
Obviously showing working out for normal distribution stuff & probability.
For line of regression I just get my a & b from the calculator.
I also get means and sd from my calculator.

you can work out normal distributions using your calculator, so you dont need to show working out ?

As mentioned above, you can get full marks for things like the correlation coefficient and the least squares regression line with no working. The flipside of this is that if you have the wrong answer (easy to do, anyone can key in an incorrect value), then you get nothing. It's always a good idea to show some working - at the very least, you should do the calculation twice, entering all of the data again, to make sure that you get the same answer.

From the most recent S1 mark scheme;

No Method Shown

Where the question specifically requires a particular method to be used, we must usually see evidence of use of this method for any marks to be awarded.

Where the answer can be reasonably obtained without showing working and it is very unlikely that the correct answer can be obtained by using an incorrect method, we must award full marks. However, the obvious penalty to candidates showing no working is that incorrect answers, however close, earn no marks.

Where a question asks the candidate to state or write down a result, no method need be shown for full marks.

Where the permitted calculator has functions which reasonably allow the solution of the question directly, the correct answer without working earns full marks, unless it is given to less than the degree of accuracy accepted in the mark scheme, when it gains no marks.

Otherwise we require evidence of a correct method for any marks to be awarded.

could you please explain this ?

thanks, will appreciate this

Not really sure what you want me to explain! It's a direct quote from the most recent S1 mark scheme, and seems pretty clear to me. What in particular do you want clarifying?

does this mean you dont have to show working then ? as long as you got the right answer?
