Question 84

A researcher investigated the effect of environmental noise on cognitive performance. Participants were asked to solve anagrams in either a quiet room (Condition A) or a room with background chatter (Condition B).

The results of the study are shown in Table 1 below.

Table 1: Performance on an anagram-solving task under two different noise conditions

	Condition A (Quiet Room)	Condition B (Noisy Room)
Mean number of anagrams solved	8.4	5.2
Standard deviation	1.85	1.82

What conclusions might be drawn from the data in Table 1? Refer to both the means and standard deviations in your answer.
