Step-by-Step Guide to Performing a Hypothesis Test by Hand
Hypotheses - Data - Test statistic - P-value - Interpretation - Conclusion
1. State the parameter of interest (symbol and words).
e.g., is it #1 - #2 or p1 - P2?
2. State the null hypothesis, Ho.
3. State the alternative hypothesis, H1.
e.g., is it H1: 1 -12 = 0 or H1: 14 -12 >0 or Hy: 14 -12 <0?
4. State the estimate and its value.
5. Calculate the test statistic:
e.g., for a t-test statistic:
. Use to = estimate - hypothesised value
std error
Write down the estimate and the hypothesised value
Use the appropriate standard error. (Will be provided)
. Calculate to.
6. Estimate the P-value. (Will be provided)
7. Interpret the P-value.
8. Calculate the confidence interval.
9. Interpret the confidence interval using plain English.
10. Give an overall conclusion.
