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. Type of line graph that shows frequency distributions






2. 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.






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






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






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






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






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






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






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






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






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






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






13. We overestimate our accuracy and our changes of success and ability to predict and explain






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






15. Perception of relationship where none exists.






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






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






18. 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.






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






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






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






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






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






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






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






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






27. 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






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






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






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






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






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






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






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






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






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






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






38. Sample drawn in such a way that known subgroups within a population are represented in proportion to their numbers in general population






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






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






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






42. 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






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






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






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






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






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






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






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






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