    • Questions to find answers to:

      • What kind of result would a null hypothesis give?
      • What is the alternate hypothesis?
      • What kind of result would support the alternate hypothesis?
      • What is the probability that a null hypothesis would give a result which would support the alternate hypothesis?

      If the probability of the null hypothesis for a result is below 5% then the result is statistically significant and the null hypothesis can be rejected. That doesn’t mean that the alternate hypothesis is true though.

      What to do:

      1. Calculate probability that a null hypothesis would give a trait score.
      2. Calculate probability that a null hypothesis would give a type score.

      How to do it:

      1. Calculate probability that a null hypothesis would give a trait score.

      • Determine distribution of random answers and trait score. No assumptions.

      2. Calculate probability that a null hypothesis would give a type score.

      • Determine distribution of random answers and type score. No assumptions.
      • Determine distribution of random random trait scores and type score. Assumes: 1. People make 75% correct answers. 2. Questions for a trait is correlated.
      • Determine distribution of random trait + inverted trait and type score. Assumes: 1. People make 75% correct answers. 2. Questions for a trait is correlated. 3. Questions for a trait and it’s inverted trait is anti-correlated.
