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






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






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






4. 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






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






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






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






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






9. Perception of relationship where none exists.






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






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






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






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






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






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






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






17. 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.






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






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






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






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






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






23. 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.






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






25. 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)






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






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






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






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






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






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






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






33. 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.






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






35. 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






36. Type of line graph that shows frequency distributions






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






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






39. 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






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






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






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






43. 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






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






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






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






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






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






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