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






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






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






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






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






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






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






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






10. 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






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






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






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






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






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






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






17. Data with an absolute 0. Ratios are meaningful. (Length - Width - Weight - Distance)






18. 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.






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






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






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






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






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






24. 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.






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






26. View that science flourishes through observation and experiment.






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






28. Arithmetic average of a distribution -






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






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






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






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






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






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






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






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






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






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






39. Bar graph that shows frequency distributions






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






41. 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






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






43. 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.






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






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






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






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






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






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






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