A cross-plot of the matched observations is given in figure 10. The regression was not
statistically significant (p=0.55, r
2
=0.004) and there was significant scatter around a fairly small
pH range within the observations. There were slightly more SAMI-pH observation below the
reference value (51) than above (33).
