  1. 1Branch of scienceStatistics (singular sense)
  2. 2A set of numerical dataStatistics (plural sense)
  3. 3A collection of all elements under consideration in a statistical studyPopulation
  4. 4A part or a subset of the population from which data are collectedSample
  5. 5A characteristic or attribute of elements which can assume different values for the different elements in the collectionVariables
  6. 6Do not varyconstants
  7. 7When a variable is manipulated by an experimenterIndependent Variable
  8. 8In non-experimental research, the Independent Variable is also calledExplanatory Variable or Predictor Variable
  9. 9Changed by another variableDependent variable
  10. 10In non-experimental research, the dependent variable is also calledOutcome variable or Criterion
  11. 11Mediate the independent variable's prediction of the dependent variableModerator variables
  12. 12realized value of a variableObservation
  13. 13collection of all observationsData
  14. 14data in its original formRaw Data
  15. 15data arranged either from highest to lowest or from lowest to highestArray
  16. 16a numerical characteristic of a populationParameter
  17. 17a numerical characteristic of a sampleStatistic
  18. 18an expectation about events based on generalizations of the assumed relationships between variablesHypotheses
  19. 19takes a general expectation - perhaps from a fully developed theory - and predicts what would be expected in the new applicationHypothesis
  20. 20Four Requirements of Hypotheses1. Hypotheses must state relationships between variables
    2. Hypotheses must be consistent with what is known in the literature
    3. Hypotheses must be testable using specific information gathered
    4. Hypotheses must be clear, grammatical, unambiguous declarative sentences
  21. 21Types of HypothesesNull and Material
  22. 22states that there is no relationship between the variablesNull Hypothesis
  23. 23referred to often as the research hypothesis that states that there is a relationship between variablesMaterial Hypothesis
  24. 24Two Forms of Material HypothesesNondirectional and Directional
  25. 25states that there will be some kind of relationship between the variablesNondirectional
  26. 26other name for nondirectional hypothesisTwo-tailed Hypothesis
  27. 27states that there will be some kind of relationship between the variables and states the form of the differencesdirectional hypothesis
  28. 28other name for directional hypothesisone-tailed hypothesis
  29. 29other term for null hpothesesstatistical hypotheses
  30. 30other term for material hypothesesresearch hypotheses
  31. 31summarizes the collection of seemingly related observations and experiencesConception
  32. 32Agreeing on what terms meanConceptualization
  33. 33Result of conceptualizationConcept
  34. 34theoretical creations that are based on observations but cannot be observed directly or indirectlyConstructs
  35. 35True or false: A concept is a construct - something we create and agree upon based on mental imagesTrue
  36. 36process of development and clarification of concepts ; clarifying one's concepts with words and examples and arriving at PRECISE VERBAL DEFINITIONSConceptualization
  37. 37The process through which we specify what we mean when we use particular terms in researchConceptualization
  38. 38we classify meanings into different groups, such groups are calledDimensions
  39. 39When a dimension is not directly observable, we useIndicators
  40. 40a sign of the presence or absence of the concept we are studyingIndicators
  41. 41Difference between concept dimension and indicatorLevel of abstraction
  42. 42TRUE or FALSE: BOTH DIMENSION AND INDICATOR CAN BE VARIABLESTRUE
  43. 43describes how a concept will be measuredOperationalization
  44. 44Operationalization choicesRange of Variation
    Precision of Variation
  45. 45Two Major Fields of StatisticsApplied and Mathematical
  46. 46Concerned with procedure and techniques used in the collection, presentation, organization, analysis, and interpretation of dataApplied Statistics
  47. 47Concerned with the development of mathematical foundations of the methods used in applied statistics.Mathematical statistics
  48. 48Two Areas of Interest Under Applied StatisticsDescriptive and Inferential
  49. 49Includes all the techniques used in organizing, summarizing, and presenting the data on handDescriptive statistics
  50. 50Includes all the techniques used in analyzing the sample data that will lead to generalizations about a population from which the sample cameInferential statistics
