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






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






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






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






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






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






8. 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.






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






10. 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






11. 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.






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






13. Bar graph that shows frequency distributions






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






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






16. 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






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






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






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






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






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






22. 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.






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






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






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






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






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






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






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






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






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






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






33. Data of categories only. Data cannot be arranged in an ordering scheme. (Gender - Race - Religion)






34. 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






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






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






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






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






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






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






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






42. 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






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






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






45. 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.






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






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






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






49. 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.






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