Research Methods

Subject : business-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Researchers takes subjects & conditions as they naturally occur - with little if any control over what happens. no random assignment so no cause and effect can be determined






2. Procedure in which info that could introduce bias the result is withheld from participants - but experimenter will be in full possession of facts






3. Expectations by researcher that might influence results of experiment or its interpretation






4. Relationship that exists when one set of data values increases while the other decreases






5. Data of categories only. Data cannot be arranged in an ordering scheme. (Gender - Race - Religion)






6. Skewed distribution with many more scores on the higher end of the distribution






7. Skewed distribution where data has many more scores toward the lower end of the distribution






8. Condition of experiment that exposes participants to treatment - that is - to one version of the IV






9. We overestimate our accuracy and our changes of success and ability to predict and explain






10. Tendency to believe - after learning an outcome - that one would have foreseen it.






11. If you take the same test 2x's & you get the same results it shows ______ reliability






12. Research method in which investigator manipulates one or more factors (IV) to observe effect on some behavior or mental process (DV)






13. In a normal distribution it tells you how far a number is above or below mean in terms of standard deviations.






14. Measures whether a test looks like it tests what it is supposed to test as determined by a quick look or evaluation by a non expert






15. Assigning participants to experimental and control conditions by chance - thus minimizing preexisting differences between those assigned to the different groups






16. Condition of experiment that contrasts with experimental condition and serves as a comparison for evaluating the effect of the treatment.






17. People of different ages are compared to one another at a single point in time






18. Research method in which info is obtained by asking many individuals a fixed set of questions






19. Data with an absolute 0. Ratios are meaningful. (Length - Width - Weight - Distance)






20. Statistical measure of strength of association between two variables ranging from -1.0 to 1.0






21. Degree to which test is representative of total domain its supposed to cover.






22. All cases in a group - from which samples may be drawn for a study






23. Statement that describes how to measure a particular variable or define a particular term specifically in a study






24. Occur when the questions asked on a sample survey are confusing or leading






25. In-depth - intensive investigation of individual or small group of people which involves interviews and personal interpretations by researcher. It may also be supplemented with psychological or medical tests






26. Statement of procedures used to explain research variables in enough detail to allow for replication






27. Factors in an experiment that are unchanged for both the control group and the experimental group






28. Repeating of research study to determine if its finding extends to other participants and circumstances






29. Experimental procedure in which both research participants and research staff are ignorant about whether the research participants have received the treatment or a placebo.






30. A test is divided into 2 halves and scores on the halves are compared to see if test is consistent within itself. Ex. compare odds & evens






31. Tendency to overestimate extent to which others share our beliefs and behaviors






32. A type of reliability - where different versions of same instrument are used and scores are compared






33. Type of line graph that shows frequency distributions






34. Computed measure of how much scores vary around the mean score.






35. Association between increases in one variable and decreases in another






36. When a specific word used in a question affects how respondents answer the question or the order of the questions






37. Experimental factor that is manipulated; variable whose effect is being studied.






38. Differences between values can be found - but is NO absolute ZERO. Examples: temperature F - time






39. Extent to which a test measures or predicts what it is supposed to - test accuracy






40. Results of experiment are SIGNIFICANT - they are not likely caused by chance






41. Graphed cluster of dots - each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables.






42. Set of assumptions used to explain phenomena & offered for scientific study






43. Assigning participants to experimental and control conditions by chance - thus minimizing preexisting differences between those assigned to different groups.






44. Sample drawn in such a way that known subgroups within a population are represented in proportion to their numbers in general population






45. Perception of a correlation between variables where none exists.






46. Form of validity in which a psychological measure is able to predict some future behavior or is meaningfully related to some other measure






47. Most frequently occurring score(s) in a distribution.






48. More than one individual scores same test - regardless of who rates test - scores should be the same for _____ reliability






49. Method by which participants are misinformed or misled about study's methods and purposes - must be told truth about this in debriefing






50. Any selection method that results in subset of the population (sample) that is not representative - and/or not random
