Alternative Hypotheses: Main Ideas!!!
In Statistics, when we do Hypothesis Testing, we are supposed to have two hypotheses: A primary, or Null Hypothesis and an Alternative Hypothesis. This StatQuest explains why we need the Alternative Hypothesis, even though Hypothesis Testing tends to focus on the Null.
NOTE: This StatQuest follows up on Hypothesis Testing and the Null Hypothesis: https://youtu.be/0oc49DyA3hU
