An investigator tested the relationship of difficulty of a task on task performance. There were 24 participants. Six were told the task was low difficulty, six were told it was moderate difficulty, six were told it was high difficulty, and the last six were not given any information. Scores range for 0 to 10, with higher values indicating better performance. The data:
Low Moderate High No Information
8—–6—–4—–4
7—–7—–1—–5
5—–4——2—–5
8—–5—–4—–6
9—–4—–6—–8
7—–6—–3—–6
Test for a relationship between the supposed task difficulty and task performance using a one-way analysis of variance.
This is actually from Experimental Design class II. It is statistics.
