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. 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






2. Type of line graph that shows frequency distributions






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






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






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






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






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






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






9. 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






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






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






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






13. Bar graph that shows frequency distributions






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






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






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






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






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






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






20. 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






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






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






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






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






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






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






27. 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)






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






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






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






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






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






33. 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






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






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






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






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






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






39. 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.






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






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






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






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






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






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






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






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






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






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






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