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. Statistical method for making simultaneous comparisons between two or more means






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






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






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






5. Research in which the same people are re-studied and re-tested over a long period






6. 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.






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






8. 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






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






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






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






12. Sample that fairly represents a population because each member has an equal chance of inclusion.






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






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






15. Procedure that ensures every person in a population has an equal chance of being chosen to participate






16. Percentage of scores falling at or below a specific score.






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






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






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






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






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






22. Hypothesis that predicts NO relationship between variables. The aim of research is to reject this hypothesis






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






24. View that science flourishes through observation and experiment.






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






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






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






28. Bar graph that shows frequency distributions






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






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






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






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






33. Perception of relationship where none exists.






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






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






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






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






38. A research method that looks like an experiment BUT subjects are not randomly assigned to control and experimental groups (no cause and effect can be drawn)






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






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






41. Extent to which the findings from one group (or sample) can be generalized or applied to other groups (or population






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






43. 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






44. Descriptive research that involves observing and recording behavior without trying to manipulate and control the situation.






45. Effects of being born and raised in a particular time or situation where all other members of your group has similar experiences makes your group unique from others






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






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






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






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






50. 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.
