An estimate of the energy produced when a fuel burns can be made by burning
the fuel under a container holding water and measuring the temperature rise of
the water.
a) What type of material should the container be made of? Explain your answer.
b) Why does this method give an estimate rather than an accurate value?
c) How can the accuracy of this method be improved?

a) Mostly, all shipping containers are made from steel and have closed-top with hinged doors. They have corrugated walls on the top and bottom sides and are welded to the rails and end frames.
b) Bias in Statistics is defined as the difference between the expected value of a statistic and the true value of the corresponding parameter. Therefore, the bias is a measure of the systematic error of an estimator.
c) The accuracy can be improved through the experimental method if each single measurement is made more accurate, e.g. through the choice of equipment. Implementing a method that reduces systematic errors will improve accuracy.
