Across
- 3. involve asking face to face questions (e.g. questions)
- 4. where participants give information about themselves without researcher interference. (e.g. Questionnaires/interviews)
- 6. (two-tailed) predicts there will be a difference, but does not predict the direction of the results. So the independant variable will have an effect on the dependant variable but the direction of the effect wont be specified.
- 10. statistics, numbers, large amounts of data.
- 14. allow participants to answer with their own words.
- 15. an increase in one variable tend to be associated with an increase in the other variable.
- 16. a hypothesis that states that there is no relationship between the two variables being studied, therefore the results would be due to chance and are not significant.
- 17. in depth, rich in detail data.
- 18. formal interview, where questions are set in standardized order and based on closed ended questions.
- 20. identifies the purpose of an investigation.
- 21. an increase in one variable tends to be associated with the decrease of another variable.
- 23. volunteer or self-selected sampling involves people volunteering to take part. They select themselves as participants, often by replying to adverts.
- 24. a hypothesis that states that there is a relationship between the two variables being studied, therefore the results are not due to chance and they are significant.
- 25. detailed, in-depth investigations of one individual or small group.
- 26. where each member of a population has equal chance of being selected, resulting in a sample selected in an unbiased fashion.
- 27. a small scale reproduction of a population, it involves dividing a population into characteristics important for the research.
Down
- 1. association/ the measure of the extent to which two co-variables are related or have a relationship.
- 2. measure the strength and direction of relationships between co-variables.
- 5. tests the effects that an independent variable has upon a dependent variable.
- 7. involves taking every nth person from a list to create a sample, involving calculating the size of the population and then assessing what size the sample needs to be to work out what the sampling interval is.
- 8. the numeric way a correlation is expressed.
- 9. (one-tailed) a type of alternative hypotheses, which predicts the direction of the results or the nature of the effect.
- 11. more like a guided conversation with no standardized question set that has to be specifically followed.
- 12. involves selecting participants who are willing and available to take apart.
- 13. a precise, testable statement of what the researchers predict will be the outcome.
- 19. the total group of individuals from which the sample might be drawn.
- 22. involve simple 'yes' 'no' answers.
