  1. Ranking based on mean scores. “Count” refers to the number of times respondents indicated they had endorsed the factor in their own work. The “Statistically different?” column tests if the mean of the higher ranked factor is significantly different from the next lowest ranked factor using paired t-tests, where ***p < 0.001 and ns p > 0.05.
