This is a helpful guide on practical skills for your physics ISAs.

I advise you read through the OCR Practical Skills Handbook.  It is from that support material and own knowledge that information has come from.

1 - Measurement and observation

The minimum number of observations to be made is 6.  This is for a linear line to be clear and 9 is the expected number of readings for a curve to be clear.  You will not be penalised if you use 6 readings, so use this number unless you feel you should do more.  Never do less than 6 readings.  Use normal intervals between the readings, such as 5(units) or 10(units).  Do not use something like 7(units).

Now, also in the task it will provide you with a range of data to be taking values from and ensure you make the readings within this range.

You're expected to make repeated readings and then take the average from these readings.  Take three to ensure you get a good average that you can see any outliers on.  With two results that are…
