Question

(1 point)
• data collected from a controlled experiment that has been reproduced in several different labs data collected from a thousand individuals that cannot be reproduced under different circumstances
• data from a single observation of an event that has not been witnessed again
O data reported by a world-renowned expert that cannot be reproduced in a different lab

Answer 1

The most reliable and valid piece of evidence among the options provided is:

• data collected from a controlled experiment that has been reproduced in several different labs.

This type of evidence is considered reliable and valid because controlled experiments minimize confounding variables and biases, and the fact that it has been reproduced in different labs indicates that the findings are robust and can be generalized beyond the initial study. Reproducibility is a key criterion for scientific validity.
