Previous research shows that, in humans, the pelvic opening tends to be wider in females than males 1. Generate a hypothesis about what cause this pattern (pelvis wider in females than in males).

2. Describe the type or types of data you would ideally collect to test this hypothesis

3. Describe what hypothesis data might support the hypothesis (For example, the hypothesis would be supported if we found data that indicated)

4. Describe what hypothetical data might regret the hypothesis and how would you rewrite your hypothesis to account for your findings and begin again.

1. Pelvis is wider in females due to it is an anatomical feature that allows the childbirth

2. A study aimed at determining if the size of the pelvis shows association with problems during childbirth

3. Females with smaller pelvis frequently have problems during childbirth

4. Populational biases in the data regarding ethnicity, age, etc

Explanation:  

A hypothesis is a proposed explanation for a given phenomenon from the real world. A scientific hypothesis needs to be tested by experimentation or observational procedures. A good hypothesis must fulfill two key requirements  1- it must be-testable, i.e., capable of being proved by using the scientific method, and 2-falsifiable, i.e., it must have a possible negative answer.
