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. Variable not relevant to what you are studying that has unplanned effect on DV. It may influence results - but all conditions are effected so it does not create bias.






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






3. 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.






4. 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






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






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






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






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






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






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






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






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






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






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






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






16. Symbol used for Pearson Correlation Coefficient ranges from -1.0 to +1.0






17. Perception of relationship where none exists.






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






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






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






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






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






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






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






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






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






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






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






29. Experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition - which is assumed to be an active agent.






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






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






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






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






34. 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.






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






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






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






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






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






40. 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






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






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






43. Indication of how likely a result obtained occurred by chance - expressed as p or sig.






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






45. Giving participants in a research study a complete explanation of the study after the study is completed needed for deception






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






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






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






49. 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.






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