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. Relationship between variables in which as one variable increases - the other also increases - OR as one decreases so does the other. Both variables move in the same direction.






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






3. Subset of a population in which every element in the population has an equal chance of being selected






4. 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.






5. Procedure for statistically combining results of many different research studies






6. The tendency for people to behave differently when they know they are being studied






7. Measure of the extent to which two factors vary together which can be positive or negative or non






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






9. 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






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






11. Extent to which a test yields consistent results - a measure is repeatable






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






13. Bell-shaped curve that results when values of a trait in a population are plotted against their frequency






14. Not rejecting null hypothesis when in fact we should have rejected it - a false negative






15. 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






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






17. Variables other than IV that participants in - one group have that makes them different - from the other group. Two variables linked together in a way that makes it difficult to sort out their specific effects.






18. Series of steps followed to solve problems including collecting data - formulating a hypothesis - testing the hypothesis - and stating conclusions






19. 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






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






21. 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






22. Rejecting null hypothesis when it is actually true - a false positive






23. Difference between highest and lowest scores in a distribution.






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






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






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






27. Arithmetic average of a distribution -






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






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






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






31. Testable and falsifiable prediction - often implied by a theory






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






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






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






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






36. Tendency to give socially approved answers to questions about oneself.






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






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






39. Measuring device or procedure designed to measure psychology-related variables. A measurement that results in a score or result that is standardized






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






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






42. The probability level which forms basis for deciding if results are statistically significant (not due to chance).






43. Change in subject's behavior caused simply by awareness of being studied






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






45. Middle score in a distribution; half scores are above it and half are below it.






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






47. Research project designed to discover degree to which two variables are related to each other






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






49. Perception of relationship where none exists.






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