13. Conclusions from both tests (item (7) and item (10):

Arusha and Moshi perform well on the intra-sex and inter-sex GSC integrity tests and less well on the SD of actual data points to average values within the GSC tests. Dar performed badly on the GSC integrity and quite well on the variability.

In general, and particularly for Dar, it appears that some improvement of data collection practices may be required. Also some changes in sampling procedure may be required.

It also appears that the use of relatively basic data processing techniques may be resulting in a loss of accuracy, i.e. better data smoothing and or data averaging techniques are required.
