Testing

  • by Nyaradzo Mvududu

    Two groups in random selection
    The differences under inspection
    On an interval scale
    And a test with one tail
    The hypothesis suffers rejection

  • Students learn the ideas of hypothesis testing in an activity where they guess which of three sodas is the different one.

    He asks, “How can you mix social justice with teaching statistics?”
    I’m thinking: how can you not?
    How better to illuminate
    deviation from expected values?

    He says, “But it’s not neutral.”
    Like it’s natural and neutral to teach from books
    based on baseball, playing cards, and flatscreen TVs
    rather than view by neighborhood things like

    incidence of asthma or
    incidents of racial profiling.
    We’ve been testing
    a null that dulls 

    by what’s normalized
    as if the type 
    1 error
    is always worse.

    When he says social justice is beyond our scope,
    I want to ask: do you mean
    our discipline or
    our humanity?

     

  • Jan: I predict conventional p-value usage will decrease.
    Lainie: You sound like a psychic.
    Jan: How so?
    Lainie: The "p" should be silent!
