Across
- 5. a trial run of research with a small number of p's allow researchers to make necessary adjustments and to save wasting valuable resources
- 9. p's are selected in a systematic way from the target population
- 13. the validity of a study outside the research situation and the extent to which the findings can be generalised

- 8. when people are aware that they are being studied
- 10. a way of controlling for order effects by having half the p's complete condition a followed by conditino b; the other p's complete condition b followed by condition a
- 11. the same group of p's is used in each of the conditions
- 12. asking whoever whoever is available and willing to participate
- 14. the extent to which a technique measures what it is supposed to measure
- 17. the sample is amde in proportion to the types of people in the population
