Hypothesis Testing: How to Recognize Ho & Ha

Click For Summary
SUMMARY

Hypothesis testing involves recognizing the null hypothesis (Ho) and the alternative hypothesis (Ha). The null hypothesis is the statement that is tested and potentially falsified through empirical observations. To successfully falsify Ho, one must demonstrate that the observed data is unlikely to have occurred by random chance, typically through statistical analysis. Resources such as Wikipedia and HyperStat provide foundational knowledge on evaluating hypotheses.

PREREQUISITES
  • Understanding of statistical significance
  • Familiarity with empirical observations
  • Basic knowledge of probability theory
  • Ability to interpret statistical data
NEXT STEPS
  • Study the concept of p-values in hypothesis testing
  • Learn about Type I and Type II errors in statistics
  • Explore different statistical tests (e.g., t-tests, chi-square tests)
  • Review case studies on hypothesis testing applications
USEFUL FOR

Students in statistics, researchers conducting empirical studies, and professionals in data analysis who need to understand hypothesis testing methodologies.

I really don't understand hypothesis testing.

How do I recognize which one is Ho and Ha in a problem?
Is there a particular trick to facilitate my lfie?

Null is the hypo. that you are attempting to falsify through your empirical observations. To falsify the null, you need to "prove" that your observations are not due to pure chance (or the probability with which they could be pure chance is low).
