M2-OQ1 The theory of probability can be used for:

(a) Mistakes; (b) Systematic errors;

(c) Accidental errors; (d) None of the above

M2-OQ2 Write whether the following statements are true (T) or false (F)

(a)  The sign of correction is always opposite to that of the error.

(b) An accidental error is cumulative.

(c)  A discrepancy is the same as a mistake.

(d)  The true error of a measurement cannot be found.

(e)  The residual is the same as variation.

(f)  The most probable error is always less than the standard error.

(g) The standard deviation has the probability of 50%.

M2-OQ3 Write whether the following statements are true (T) or false (F).

(a) A measurement is said to have high precision if it has a small deviation.

(b) High precision always means high accuracy.

(c) The true value of a quantity is the mean of an infinite number of observations.

(d) The probability of true error being less than the most probable error is 68.3%.

(e) The spread of the probability curve increases as the precision increases.
