A study at Bentley College, a large business
school in the eastern United States, examined students’ anxiety
levels toward the
subject of accounting (“Determinants of
Accounting Anxiety in Business Students,”
J. College Teach. Learn. 2004). A representative sample of 1020
students completed the Accounting Anxiety Rating Scale
(AARS) questionnaire; higher scores (out
of 100) indicate greater anxiety. Summary
data broken down by grade level appears in
the accompanying table.
Class level n x s
Freshman 86 48.95 9.13
Sophomore 224 51.45 11.29
Junior 225 52.89 11.32
Senior 198 52.92 11.32
Graduate 287 45.55 10.10
a. Comment on the plausibility (or necessity) of the normality and
equal variance
assumptions for this example.
b. Test at a = .05 the hypothesis that the
mean accounting anxiety level for
business students varies by class level.
