Marking points from the official mark scheme (May/June 2019). The mark or mark type is shown in brackets.

1. [2] 2 marks for a one-tailed hypothesis with both variables if correlational, 2 levels of IV and a DV if experimental with at least one operationalised variable
2. 1 mark for a one-tailed hypothesis with 2 levels of IV and a DV
3. 0 marks for a non-directional (two-tailed) hypothesis
4. 0 marks for a null hypothesis
5. Hypothesis may be experimental or correlational
6. Adults are more likely to play internet-based games than younger people = 1 (experimental not operationalised)
7. The older you are the more likely you are to play internet games = 1 mark (correlational not operationalised)
8. Older people/adults are more likely to play internet based games for more than 2 hours per day than younger people / children. = 2 marks
9. 12 year olds are more likely to play internet based games than people over 40 = 2 marks
10. The older you are in years the more likely you are to play an internet game. = 2 marks
11. The older you are the less likely you are to play an internet game for more than 8 hours a day. = 2 marks
12. [2] 1 mark for identifying a suitable population (by description or example)
13. 2nd mark for detail (e.g. stated age range) OR second feature of the population
14. internet users with a wide are range / all the internet users in one town / all social media/Snapchat/Twitter users;
