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






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






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






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






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






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






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






8. Type of line graph that shows frequency distributions






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






10. 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






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






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






13. 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






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






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






16. 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






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






18. 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.






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






20. 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)






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






22. Bar graph that shows frequency distributions






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






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






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






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






27. 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.






28. 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






29. View that science flourishes through observation and experiment.






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






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






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






33. Factors in an experiment that are unchanged for both the control group and the experimental group






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






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






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






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






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






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






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






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






42. 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.






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






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






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






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






47. Arithmetic average of a distribution -






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






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






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