Multi-way analysis of variance of HIT and E based on different ages, layers and locations. The (a) and (c) show the statistical description of HIT and E of ages at the same layers and location. The (b) and (d) show the statistical description of HIT and E of location at the same layers and ages. And the group with statistical significance are connected by straight lines.
