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