question
an experiment was performed by a scientific research team to determine the association between a predatory birds hunting technique and average flight time.
which of the following could be a potential confounding variable in the experiment?
select the correct answer below:
○ scientific research team
○ average flight time
○ wingspan
○ type of prey

Explanation:

A confounding variable is a factor that affects both the independent variable (hunting technique) and dependent variable (average flight time), distorting their true association.

• The research team does not impact the bird's flight or hunting.
• Average flight time is the dependent variable, not a confounder.
• Wingspan affects flight time but not hunting technique directly.
• Type of prey influences both: different prey may require distinct hunting techniques, and chasing certain prey changes flight time.

Answer:

type of prey
