Accepted Answer

normal equation

Answer

observation equation

Answer

conditional equation

Answer

(d ) none of these.

Question 5

The law of weight applicable to the Method of Least squares error, is

Accepted Answer

The weight of the product of any quantity multiplied by a constant is equal to the weight of that quantity divided by the square of that constant.

Answer

The weight of the arithmetic mean of a number of observations of unit weight, is equal to the number of observations

Answer

The weight of the weighted arithmetic mean of a number of observations, is equal to the sum of the individual weights of observations

Answer

(c ) The weight of the sum of the quantities added algebraically is equal to the reciprocal of the sum of the reciprocals of the individual weights
