Table 5: Table 5: Non-parametric test values for test D, E and F regarding group 2 (buy lunch at school) and group 3 (sometimes go hungry).
* = Statistically significant at the 5% level (p>0.05 but p<0.01)
** = Statistically significant at the 1% level (p<0.01) Effect size – r = 0.10 - 0.29 small; r = 0.30 - 0.49; moderate; r = 0.5+ large.
