  8. True or false

    Sample data reveals something about the unit.
    False

    Sample data reveals something about the population.
  9. True or false

    Sample data may not always be true as it depends on the way a sample is drawn.
    True
  10. True or False

    If the sample is a replica of the population then, the statistic is true.
    True
  11. True or False

    If the sample is biased then, the statistics cannot be true.
    True

  44. Statistics has 2 major areas:
    • Descriptive statistics
    • Inferential/ Indicative Statistics
  45. Can mean that the data itself or some numerical computations derived from a set of data.
    Statistics
  46. An area of statistics that summarizes to make sense of meaning of the list of numerical values. They deal largely with summary of calculations, graphical and tabular displays, and describing important features of a set of data. 

    It does not attempt to draw conclusions about anything that pertains to more than the data than themselves.
    Descriptive Statistics
  47. An area of statistics which is concerned in making generalizations for a bigger group of observations called population-based information gathered from a small group of observations or sample drawn from a given population.
    Inductive/ Inferential Statistics
