Statistical Inference Multiple Choice Questions and answers (mcqs)

 1- Discussion about Population Parameter on the basis of Sample Observations is called as: ?

(A) Statistical Inference       (B) Inferential Statistics 

Option (A) is correct.

2- The Estimator is defined as: ?

(A) Formula             (B) Value

Option (A) is correct.

Note: But, Estimate is a Value.

3- An Estimator would be Consistent If Variance of this Estimator becomes _  as n approaches infinity: ?

(A) Nine                  (B) Zero

Option (B) is correct.

4- If Efficiency > 1, then T is _ efficient: ?

(A) More                 (B) Less

Option (A) is correct.

5- T1 will be more efficient than T2 If: ?

(A) Var (T1) > Var(T2)     (B) Var(T1) < Var(T2)

Option (B) is correct.

6- BLUE is abbreviated as: ?

(A) Best Linear Unbiased Estimator   (B) Blue Light Union Enter

Option (A) is correct.

7- In BLUE, Variance is always: ?

(A) Least                (B) at most

Option (A) is correct.

8- Level of Confidence is: ?

(A) alpha                (B) 1 - alpha

Option (B) is correct.

9- Confidence Coefficient is always: ?

(A) ( 1 - alpha ) 100 %   (B) 1 - alpha

Option (A) is correct.

10- Is an Estimator a Random Variable: ?

(A) No                     (B) Yes

Option (B) is correct.

Note: Yes, Estimator is a random variable because Estimator has different Probability Distributions.

11- For Checking the Unbiasedness of Estimators T1 and T2, we should take: ?

(A) Expectation         (B) Variance

Option (A) is correct.

best of luck!
