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






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






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






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






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






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






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






9. 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)






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






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






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






13. Statistical method for making simultaneous comparisons between two or more means






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






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






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






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






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






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






20. Perception of relationship where none exists.






21. Arithmetic average of a distribution -






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






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






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






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






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






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






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






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






30. 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.






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






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






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






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






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






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






37. Bar graph that shows frequency distributions






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






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






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






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






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






43. Type of line graph that shows frequency distributions






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






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






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






47. Correlation where as one variable increases - the other also increases - or as one decreases so does the other. Both variables move in same direction.






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






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






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