scientific methods: The six basic steps in hypothesis testing

  1. Observation – male lions kill cubs
  2. Determine question of interest – why do male lions commit infanticide?
  3. hypotheses – Males kill infants to get a female to come back into estrus sooner so he can now mate with her.
  4. Make Predictions (“if…then” statements) – If males kill infants to gain access to females, then the cubs he kills should not be related to him
  5. Design, conduct and analyze experiments- collect blood samples of cubs and male lions, test paternity
  6. Evaluate the hypotheses
