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. Statement that describes how to measure a particular variable or define a particular term specifically in a study






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






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






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






5. Type of line graph that shows frequency distributions






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






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






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






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






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






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






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






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






14. Perception of relationship where none exists.






15. Data exists in categories that are ordered but differences cannot be determined or they are meaningless. (Example: 1st - 2nd - 3rd)






16. 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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






31. 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.






32. Procedure that ensures every person in a population has an equal chance of being chosen to participate






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






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






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






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






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






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






39. Arithmetic average of a distribution -






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






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






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






43. 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






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






45. View that science flourishes through observation and experiment.






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






47. 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)






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






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






50. 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.
