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






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






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






4. 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)






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






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






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






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






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






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






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






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






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






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






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






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






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






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






20. 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.






21. View that science flourishes through observation and experiment.






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






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






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






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






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






27. 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.






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






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






30. Bar graph that shows frequency distributions






31. Repeating of research study to determine if its finding extends to other participants and circumstances






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






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






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






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






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






37. 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






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






39. 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.






40. 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






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






42. Perception of relationship where none exists.






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






44. 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






45. Testable and falsifiable prediction - often implied by a theory






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






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






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






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






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