Table 5. Pre-movement theta-band spectral power (Post hoc comparisons—Age-Movement Type).
| Mean Difference | SE | stat | p | ||
|---|---|---|---|---|---|
| EA, LH | YA, LH | 0.295 | 0.438 | 42.0 (U) | 0.28 |
| EA, RH | -0.068 | 0.199 | 21.0 (W) | 0.51 | |
| YA, RH | 0.863 | 0.438 | 2.503 (t) | 0.022* | |
| YA, LH | EA, RH | -0.363 | 0.438 | 25.0 (U) | 0.032* |
| YA, RH | 0.568 | 0.199 | 7.0 (W) | 0.037* | |
| EA, RH | YA, RH | 0.931 | 0.438 | 25.0 (U) | 0.032* |
According to the results of Shapiro-Wilk normality test, the (EA,RH)-set with p = 0.029 and (YA,LH)-set with p = 0.034 did not come from the normally distributed population. Therefore, along with the unpaired t-test (t) we used non-parametric Mann-Whitney U-test (U) and Wilcoxon signed-rank test (W) to the provide the post hoc comparisons.
