    Inferential and descriptive:
    different stats with different rules
    Inferential and descriptive:
    different goals and different tools.


    What's the average height of students in this room, whom I can measure?
    Here you are describing data that you've got.

    What's the average height of students living in Australia?
    Now you are inferring something you know not.


    When reporting variation in descriptive information,
    interquartile range may be employed.
    When reporting variation in inferential information,
    standard error of the mean may fill the void.

    Power is the probability

    to reject the null (to reject the null)

    if its false indeed

    Power is the probability

    to reject the null (to reject the null)

    if its false indeed



  • Uncertainty is the prerequisite to gaining knowledge and frequently the result as well.

    Edith Hamilton (1867 – 1963)

  • … assuredly of all earthly conditions uncertainty is the most unblest …

    Fanny Kemble (1809 – 1893)

  • we have this opportunity to try to make meaning out of data ourselves, because frankly, data doesn't create meaning. We do.

    Susan Etlinger (1962 - )

  • When curiosity turns to serious matters, it’s called research.

    Marie von Ebner-Eschenbach (1830 – 1916)

  • There is so much information that our ability to focus on any piece of it is interrupted by other information, so that we bathe in information but hardly absorb or analyse it. Data are interrupted by other data before we’ve thought about the first round, and contemplating three streams of data at once may be a way to think about none of them.

    Rebecca Solnit, (1961 - )

  • Everything is data. But data isn’t everything.

    Pauline B. Bart (1930 - )

  • The ability to make sense of random data is a fundamental human attribute.

    Stephanie Winston (1935 - ) 

  • How to use facts, not how to accumulate them, is the purpose of true education.

    Pearl S. Buck (1892 – 1973)
