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. Type of line graph that shows frequency distributions






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






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






4. Percentage of scores falling at or below a specific score.






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






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






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






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






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






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






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






12. 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)






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






14. Effects of being born and raised in a particular time or situation where all other members of your group has similar experiences makes your group unique from others






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






16. 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.






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






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






19. Perception of relationship where none exists.






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






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






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






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






24. 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.






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






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






27. Bar graph that shows frequency distributions






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






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






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






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






32. 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






33. 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.






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






35. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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