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. 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.






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






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






4. 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.






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






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






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






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






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






10. 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






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






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






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






14. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






22. Bar graph that shows frequency distributions






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






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






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






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






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






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






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






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






31. 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






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






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






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






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






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






37. Skewed distribution where data has many more scores toward the lower end of the distribution






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






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






40. Tendency to believe - after learning an outcome - that one would have foreseen it.






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






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






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






44. View that science flourishes through observation and experiment.






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






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






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






48. 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.






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






50. Arithmetic average of a distribution -
