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






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






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






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






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






7. 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.






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






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






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






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






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






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






14. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






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






23. 'Fake subjects' that look & behave like real subjects in study.






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






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






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






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






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






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






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






31. Symbol used to represent the total number of subjects in a research study






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






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






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






35. 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.






36. Type of line graph that shows frequency distributions






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






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






39. 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.






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






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






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






43. 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






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






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






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






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






48. Extent to which scores suggest that a test is actually measuring an ABSTRACT theoretical idea (such as anxiety - personality - introversion - etc.).






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






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