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






2. The probability level which forms basis for deciding if results are statistically significant (not due to chance).






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






4. 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






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






6. Arithmetic average of a distribution -






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






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






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






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






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






12. 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






13. 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.






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






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






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






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






18. View that science flourishes through observation and experiment.






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






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






21. 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.






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






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






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






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






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






27. 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






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






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






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






31. Bar graph that shows frequency distributions






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






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






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






35. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






44. 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






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






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






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






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






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






50. 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.
