Question

The age of a pine tree was measured 5 times independently using a new electric probe inserted in the trees trunk. The measured values were 46 years old, 45 years old, and 47 years old. Later, the same tree was cut and by counting the growth rings, it was determined the tree was really 34 years old. Does a measurement with this new electronic device for measuring the age of trees have a larger problem with bias or reliability?

Explanation / Answer

I think that the new electric probe has a larger problem with bias as the measured values were 46,45,47 which are systematic in nature. They are all around 11-12 years more than the actual value and the standard deviation is quite less. Therefore, due to its systematic nature, we have a problem of bias here.
