-65 -52.8 -49
-64 -52.5 -48
-65 -52 -49
-64 -51 -48
-60 -52 -49
-62 -53 -49

-62 -51.8 -48
-65 -52.8 -48
-66 -52.2 -48
-62 -52.5 -48
-62 -52.5 -49
-63 -51.8 -48
-60 -51.5 -48
-61 -50.8 -48
-56 -49.8 -47

variation in mean due to change in circumstances !

your question is as good as my answer

I can see the mean value given by (max+min)/2 is always lower than the measured average; f.i. the first row is (-65-49)/2=-57 that is lower than 52.8. Supposing the sampling to get max/min and avg is the same, then the actual values are closer to the maximum rather than the minimum
