Across
- 1. The use of a mathematical or physical model to reproduce the conditions of a situation or process
- 3. The branch of statistics that involves the organization, summarization, and the display of data
- 6. A treatment is applied to part of a population and responses are observed
- 7. A subset of a population
- 9. Neither the subject nor the experimenter knows if the subject is receiving a treatment
- 11. A numeral description of a sample characteristic
- 13. When to population falls into natural occurring subgroups, each having similar characteristics
- 15. A sample in which each member of a population is assigned a number, the members of the population are ordered in some way, and then randomly selected
- 16. Every member of a population has an equal chance of being selected
- 17. A count or measure of an entire population
- 18. A technique where the subject does not know whether he/she is receiving treatment or a placebo
- 19. A sample that is drawn from a number of separate strata of the population, rather than at random from the whole population, in order that it should be representative
- 22. Occurs when an experimenter cannot tell the difference between the effects of different factors on a variable
- 25. The replication of an experiment using a large group of subjects
- 26. Qualitative or quantitative data that can be arranged in an order, were mathematical conclusions are meaningless
- 27. Is the science of collecting, organizing, analyzing, and interpreting data in order to make decisions
- 29. Consist of attributes, labels, or non-numerical entries
- 30. Is the collection of all outcomes, responses, measurements, or counts that are of interest
Down
- 2. The branch of statistics that involves using a sample to draw conclusions about a population
- 4. You can calculate meaningful differences between data, and cannot be lower than zero
- 5. Only available members of a population are sampled
- 7. A sample in which every possible sample has the same chance of being selected
- 8. Consist coming from observations, counts, measurements, or responses
- 10. A researcher observes and measures characteristics of interest in a population, but doesn’t change any variables
- 12. A count or measure of part of a population
- 14. A numerical description of a population’s characteristics
- 20. Similar to interval level of measurement except a zero and below is meaningful
- 21. Consist of numerical measurements or counts
- 23. Only qualitative data is used, no numerical computations can be made at this level
- 24. A process of randomly assigning subjects to different treatment groups
- 28. An investigation of one or more characteristics of a population
