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






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






3. 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






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






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






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






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






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






9. 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.






10. 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.






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






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






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






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






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






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






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






19. 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






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






21. Arithmetic average of a distribution -






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






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






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






25. 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






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






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






28. Bar graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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