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






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






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






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






5. Perception of relationship where none exists.






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






7. 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)






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






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






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






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






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






13. 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






14. 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






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






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






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






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






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






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






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






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






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






24. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






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






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






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






37. View that science flourishes through observation and experiment.






38. 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






39. People of different ages are compared to one another at a single point in time






40. 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.






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






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






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






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






45. 'Fake subjects' that look & behave like real subjects in study.






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






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






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






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






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