Across
- 3. classifies data into mutually exclusive (nonover-lapping) categories in which no order or ranking can be imposed on the data
- 4. values that can be counted
- 5. Variables that are not measurement variables
- 6. the researcher manipulates one of the variables and tries to determine how the manipulation influences other variables
- 9. consists of all subjects(human or otherwise) that are being studied
- 10. consists of generalizing from samples to populations, performing estimations and hypothesis tests, determining relationships among variables, and making predictions
- 12. the researcher merely observes what is happening or what has happened in the past and tries to draw conclusions based on these observations
- 15. variables that are measurement variables
- 16. possesses all the characteristics of interval measurement, and there exists a true zero. in addition, true ratios exist when the same variable is measured on two different members of the population
- 18. sample a sampling plan used when mutually homogeneous yet internally heterogeneous groupings are evident in a statistical population
- 19. a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability
- 20. is one that influences the dependent or outcome variable but was not separated from the independent variable
Down
- 1. is a characteristic or attribute that can assume different values
- 2. consists of the collection, summarization, and presentation of data
- 7. a group of subjects selected from a population
- 8. can assume an infinite number of values between any two specific values. they are obtained by measuring. they often include fractions and decimals.
- 11. classifies data into categories that can be ranked; however, precise differences between the ranks do not exist
- 13. ranks data, and precise differences between units of measure do exist; however, there is no meaningful zero.
- 14. in an experimental study is the one that is being manipulated by the researcher.
- 17. the science of conducting studies to collect, organize, summarize, analyze, and draw conclusions from data
