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. Researchers takes subjects & conditions as they naturally occur - with little if any control over what happens. no random assignment so no cause and effect can be determined






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






3. 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)






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






5. Arithmetic average of a distribution -






6. 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.






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






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






9. Research method in which info is obtained by asking many individuals a fixed set of questions






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






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






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






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






14. 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






15. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






34. Perception of relationship where none exists.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






49. Bar graph that shows frequency distributions






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