Across
  1. 2. the average score in a sample of scores which describes a typical score
  2. 4. opposite of the Null Hypothesis
  3. 6. sing descriptive statistics derived from a population
  4. 11. method of recording & organizing & interpreting data
  5. 15. prediction of the direction of the treatments effect
  6. 20. the “independent” variables in quasi-experiments
  7. 22. when using descriptive statistics that are derived from a sample
  8. 23. any measure that varies or can potentially vary in value
  9. 25. unique participants or subjects in a ample
  10. 26. total # of people or animals or things of interest in or you generalize or apply findings
  11. 30. variable whose value depends on the value of one or more other variable
  12. 31. when the direction of the treatment effect is predicted
  13. 33. any body of knowledge developed through scientific method
  14. 34. observations that are well planned & carefully measured & accurately recorded
  15. 36. E.V. that changes along with or covaries with the I.V.& which can cause changes in the D.V.
  16. 39. event that can be directly observed
  17. 41. a variable whose value is predicted to affect the dependent variable
  18. 42. studying how the presence of one variable affects the value of another variable
  19. 43. the no-drug group who eliminate anticipated effects of drug-taking as an E.V.
Down
  1. 1. human members of a sample
  2. 3. use of systematic observations of empirical events
  3. 5. study that examines the relationship between two pre-existing variables
  4. 7. manipulation of the independent variable
  5. 8. no prediction of the direction of the treatment effect
  6. 9. rejecting a true null hypothesis alpha error
  7. 10. not randomly assigning participants to the different levels of the I.V.
  8. 12. hypothesis that the independent variable does NOT have an effect on the population
  9. 13. a relationship that exists between or among variables
  10. 14. the “unlikely-ness” that that our null hypothesis is true
  11. 16. direction of the treatment effect has no prediction
  12. 17. predetermined probability level of rejecting a null hypothesis
  13. 18. rejecting a null hypothesis on the basis of the P= 0.5 or <
  14. 19. measurements of observations of empirical events which can be quantified or given #'s to represent value
  15. 21. variables other than the I.V. that could affect the value of the D.V.
  16. 24. choosing cases one at a time from population ensuring every case has an equal chance of being chosen each time
  17. 27. a statement of belief about a relationship between two or more variables
  18. 28. animals in a Sample
  19. 29. the probability of correctly rejecting a false N.H. is 1- Beta
  20. 32. hypothesis that the independent variable DOES have an effect on the population
  21. 35. wrong in not rejecting a null hypothesis that is false beta error harder to determine
  22. 37. group of scores or measures that make up a portion of population
  23. 38. an identical looking and tasting tablet that contains no drug
  24. 40. is any measure that does not vary
