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






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






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






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






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






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






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






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






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






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






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






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






13. 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






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






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






16. Type of line graph that shows frequency distributions






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






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






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






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






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






22. 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.






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






24. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






41. Bar graph that shows frequency distributions






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






43. 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






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






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






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






47. 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






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






49. Perception of relationship where none exists.






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