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. 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.






2. View that science flourishes through observation and experiment.






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






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






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






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






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






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






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






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






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






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






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






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






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






16. Arithmetic average of a distribution -






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






18. 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






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






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






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






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






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






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






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






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






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






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






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






30. Bar graph that shows frequency distributions






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






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






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






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






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






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






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






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






39. 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)






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






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






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






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






44. 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.






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






46. 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.






47. Type of line graph that shows frequency distributions






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






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






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