aLevel of significance 0.05; b1 cells (25.0%) have expected count less than 5. The minimum expected count is 3.81; cDue to lack of response (one participant responded to this question) this figure is calculated based on the continuity correction; Computed only for a 2 × 2 table with a measurement of 0.098, and therefore is statistically insignificant.
