(1) The second degree parabola is fitted to the time series when the variations are:
[A] Linear
[B] Nonlinear
[C] Random
[D] Downward
Answer: Nonlinear
(2) In fitting a second degree parabola, the value of c is not affected with the change of :
[A] Scale
[B] Origin
[C] Both (a) and (b)
[D] Neither (a) and (b)
Answer: Origin
(3) For odd number of year, formula to code the values of X by taking origin at centre is:
[A] X = year – average of years
[B] X = year – first year
[C] X = year – last year
[D] X = year – ½ average of years
Answer: X = year – average of years
(4) For even number of years when origin is in the centre and the unit of X being one year, then X can be coded as:
[A] X = (year – average of years)/2
[B] X = year – average of years
[C] X = year – 0.5 average of years
[D] X = average of years – year
Answer: X = year – average of years
(5) For even number of years when origin is in the centre and the unit of X being half year, then X can be coded as:
[A] X = year – average of years
[B] X = 2(year – average of years)
[C] X = (year – average year)/2
[D] X = year – ½ average of years
Answer: X = 2(year – average of years)

[A] Still valid
[B] Consistent
[C] No longer valid
[D] Unbiased
Answer: No longer valid
