Researchers investigated the effects of a brief 10-minute meditation session compared to a quiet rest control session on cognitive performance and physiological stress.
They found no significant difference in salivary cortisol level reductions (p>0.05p > 0.05p>0.05), but they found a highly significant difference in word-recall test scores (p≤0.01p \le 0.01p≤0.01).
Explain why the researchers did not think that they had made a Type 1 error in relation to the difference in word-recall test scores.
