In Arithmetical Increase Method, The rate of change of population with time is ?
Explanation: The rate of change of population with time is constant.
In Arithmetical Increase Method, the population after n decade can be determined by the formula ?
A. Pn = P + n. C*C
B. Pn = P - n. C
C. Pn = P * n. C
D. Pn = P + n. C
Explanation: The population after n decade can be determined by the formula : Pn = P + n. C
Incremental Increase Method is improvement over which method?
A. Geometrical Increase Method
B. Arithmetical Increase Method
C. Both A and B
D. Decreasing Rate Method
Explanation: Incremental Increase Method is improvement over Geometrical Increase Method and Arithmetical Increase Method.
The Master Plan Method is also known as?
A. Logistic Curve Method
B. Zoning Method
C. Comparative Graphical Method
D. Simple Graphical Method
Explanation: The Master Plan Method is also known as Zoning Method.
The master plans are prepared for the development of the cities for?
A. 15 to 20 years
B. 5 to 10 years
C. 15 to 25 years
D. 25 to 30 years
Explanation: The master plans are prepared for the development of the cities for 25-30 years. The population densities for various zones of the towns to be developed are also fixed. Now when the population of a particular zone is fixed, it is very easy to design the water supply schemes for the particular zones. The future development of the water works is also designed on the basis of the master plan.
What is the expression used for population forecasting by the arithmetical increase method?
A. PO (1 + R/100)^n
B. PO + n*x
C. PO + n*x + ( n(n+1)/2 )*y
D. PO – n*x
Explanation: The expression of the arithmetical increase method is given by PO+n*x, where PO is the present population, x is the average of the population increase in known decade and n is the number of decades.
Logistic method is also called as _______
A. Decreased rate of growth method
B. Incremental increase method
C. Geometrical increase method
D. Arithmetical increase method
Explanation: Logistic method is also called a decreased rate of growth method. In this method, the percentage increase in growth rate and then the percentage decrease in growth rate are founded where all populations grow according to the logistic curve.
Which method is suitable if the growth rate is decreasing and the population is reaching towards saturation?
A. Arithmetical increase method
B. Graphical comparison method
C. Zoning method
D. Decreased rate of growth method
Explanation: In decreased rate of growth method, growth rate is decreasing and the population is reaching towards saturation and is only valid when growth rate shows a downward pattern.
Which method of population forecast is suitable when extension is required for small duration and past record is available for long duration?
A. Graphical comparison method
B. Graphical extension method
C. Logistic curve method
D. Zoning method
Explanation: In the graphical extension method, a curve is drawn between population and time up to the present period, then the curve is extended from present to the future decade and the population is approximately determined from the extended part of the curve.
In Logistic Curve Method, The growth rate between point K to M follows curve of dp/dt = constant?
C. Can be true or false
D. Can not say
Explanation: The growth rate between point K to M follows curve of dp/dt = constant. The transitional curve KM also passes through the point of inflexion L
