Across
  1. 2. __________ level of measurement: Qualitative or quantitative data. Data can be arranged in order, or ranked. Differences between data entries is not meaningful
  2. 5. Consist of information coming from observations, counts, measurements, or responses.
  3. 6. __________ random sample: Every possible sample of the same size has the same chance of being selected.
  4. 7. _________ variables: Occus when an experimenter cannot tell the difference between the effects of different factors on a variable.
  5. 9. __________ study: A researcher observes and measures characteristics of interest of part of a population.
  6. 10. A count or measure of an entire population.
  7. 16. __________ - __________ Experiment where neither the subject nor the experimenter knows if the subject is receiving a treatment or a placebo.
  8. 17. __________ effect: Occurs when a subject reacts favorably, when in fact the subject has been given a disguised fake treatment.
  9. 19. ___________ statistics: Involves organizing, summarizing, and displaying data.
  10. 21. __________ data: Numerical measurements or counts.
  11. 22. __________ - __________ design: Subjects are paired up according to a similarity. One subject in the pair is randomly selected to receive one treatment while the other subject receives a different treatment.
  12. 24. __________ sample: Divide a population into groups and select a random sample from each group.
  13. 26. ___________ statistics: Involves using sample data to draw conclusions about a population.
  14. 28. A treatment is applied to part of a population, called a treatment group, and responses are observed.
  15. 30. __________ sample: Divide the population into groups and select all of the members in one or more, but not all, of the groups.
  16. 34. __________ level of measurement: Quantitative. Similar to interval level. Zero entry is an inherent zero (implies “none”). A ratio of two data values can be formed. One data value can be expressed as a multiple of another
  17. 35. A numerical description of a sample characteristic.
  18. 36. The science of collecting, organizing, analyzing, and interpreting data in order to make decisions.
  19. 37. A technique where the subject does not know whether he or she is receiving a treatment or a placebo.
Down
  1. 1. __________ data: Consists of attributes, labels, or nonnumerical entries.
  2. 3. __________ level of measurement: Qualitative data only. Categorized using names, labels, or qualities. No mathematical computations can be made
  3. 4. __________ sample: Every member of the population has an equal chance of being selected.
  4. 8. A process of randomly assigning subjects to different treatment groups.
  5. 11. A subset, or part, of the population.
  6. 12. __________ level of measurement: Quantitative data. Data can ordered. Differences between data entries is meaningful. Zero represents a position on a scale (not an inherent zero – zero does not imply “none”)
  7. 13. __________ sample: Choose a starting value at random. Then choose every kth member of the population.
  8. 14. Randomized __________ design: Divide subjects with similar characteristics into blocks, and then within each block, randomly assign subjects to treatment groups.
  9. 15. The collection of all outcomes, responses, measurements, or counts that are of interest.
  10. 18. __________ randomized design: Subjects are assigned to different treatment groups through random selection.
  11. 20. A numerical description of a population characteristic.
  12. 23. __________ sample: Choose only members of the population that are easy to get. Often leads to biased studies.
  13. 25. Uses a mathematical or physical model to reproduce the conditions of a situation or process. Often involves the use of computers.
  14. 27. The repetition of an experiment using a large group of subjects.
  15. 29. An investigation of one or more characteristics of a population. Carried out on people by asking them questions.
  16. 31. __________ group: The part of the population where a treatment is applied.
  17. 32. __________ group: The part of the population where a NO treatment is applied.
  18. 33. __________ error: The difference between the results of a sample and those of the population.
