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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






23. 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






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






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






26. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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






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






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






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






42. Perception of relationship where none exists.






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






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






45. 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.






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






47. Experimental procedure in which both research participants and research staff are ignorant about whether the research participants have received the treatment or a placebo.






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






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






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