Question

Which of the following pieces of evidence would be considered the most reliable and valid?(1 point)

data collected from a thousand individuals that cannot be reproduced under different circumstances

data reported by a world-renowned expert that cannot be reproduced in a different lab

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

data from a single observation of an event that has not been witnessed again

Answer 1

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

Reason: controlled experiments with independent replication provide both internal validity (controls for confounds) and reliability/credibility through reproducible results; the other options lack reproducibility or replication.
