Presentation transcript:

Using a GDC to Do Questions (While still scoring marks) We are going to look at past paper questions and mark schemes to see how many marks we may miss out on relying on a GDC.

12 mins

AWFW anything which falls within i.e. correct answer full marks… decreasing accuracy (typos) lose marks.

12 Mins

If you standardise you score this mark If you draw diagrams and work out the right region you might get this mark Inversing Normal for Mean or SD cannot be found on calculator

9 mins 36 seconds!

No marks lost for using calculator just accuracy.

13 mins 12 secs

Once more no marks lost but correctness in critical!

13 mins 12 secs

Answer only 1 mark! You’d need to find this anyhow for 1 mark Use of percentage points table 1 mark. Knowing formula for confidence interval Writing distribution (as entered into calculator) 1 mark Another standardising mark Answer only 1 mark!
