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






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






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






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






6. 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)






7. Perception of relationship where none exists.






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






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






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






11. 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






12. Type of line graph that shows frequency distributions






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






14. 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.






15. Descriptive research technique in which one person or a small group is studied in depth in hope of revealing universal principles






16. 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.






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






18. View that science flourishes through observation and experiment.






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






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






21. Correlation where as one variable increases - the other also increases - or as one decreases so does the other. Both variables move in same direction.






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






23. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






45. In-depth - intensive investigation of individual or small group of people which involves interviews and personal interpretations by researcher. It may also be supplemented with psychological or medical tests






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






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






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






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






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