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






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






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






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






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






6. Method by which participants are misinformed or misled about study's methods and purposes - must be told truth about this in debriefing






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






8. 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






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






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






11. Type of line graph that shows frequency distributions






12. 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.






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






14. Arithmetic average of a distribution -






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






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






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






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






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






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






21. View that science flourishes through observation and experiment.






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






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






24. 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.






25. 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






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






27. Perception of relationship where none exists.






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






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






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






31. Percentage of scores falling at or below a specific score.






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






33. 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






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






35. The tendency for people to behave differently when they know they are being studied






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






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






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






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






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






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






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






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






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






45. 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.






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






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






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






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






50. Tendency to overestimate extent to which others share our beliefs and behaviors
