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






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






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






4. 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.






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






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






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






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






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






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






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






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






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






14. 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






15. Variable that may change in response to manipulations of the IV (what is measured)






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






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






18. 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.






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






20. 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.






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






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






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






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






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






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






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






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






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






30. 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.






31. Perception of relationship where none exists.






32. View that science flourishes through observation and experiment.






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






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






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






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






37. 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)






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






39. 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.






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






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






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






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






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






45. Data exists in categories that are ordered but differences cannot be determined or they are meaningless. (Example: 1st - 2nd - 3rd)






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






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






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






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






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