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






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






3. Perception of relationship where none exists.






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






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






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






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






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






9. 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.






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






11. Type of line graph that shows frequency distributions






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






13. 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






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






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






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






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






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






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






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






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






22. View that science flourishes through observation and experiment.






23. 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.






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






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






26. 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.






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






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






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






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






31. Association between increases in one variable and decreases in another






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






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






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






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






36. 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






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






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






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






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






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






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






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






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






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






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






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






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