The mean result increased in support of a hypothesis but the data had a very large spread. What is the most appropriate interpretation?

Answer and explanation

Correct answer: There may be a trend but high uncertainty means more trials are needed

A large spread lowers confidence in the result and suggests more replication. Examine variability along with the mean.
