Question

has a proposed answer to a question, is testable/falsifiable, and has a prediction. What is missing in the following # If breastfeeding has a positive impact on brain white matter, breastfed infants will have larger white # If brain white matter volume is compared in breastfed versus bottle-fed infants, breastfed infants If breastfeeding has a positive impact on brain white matter, brain white matter volume and quality will have larger white matter volume than bottle-fed infants. can be compared in breastfed and bottle-fed infants.

Explanation / Answer

Hypothesis 1: If breastfeeding has a positive impact on brain white matter, breastfed infants would have larger white matter volume - this hypothesis lacks test or comparison and falsifiability.

Hypothesis 2: If brain white matter volume is compared in breastfed versus bottle fed infants, breastfed infants would have a larger white matter volume than bottle-fed infants - this hypothesis lacks prediction.

Hypothesis 3: If breastfeeding has a positive impact on brain white matter, brain white matter volume and quality can be compared in breastfed and bottle-fed infants - this hypothesis lack proposed answer to research questions.
