UGC NET Commerce Unit 5 PYQs, Important Questions

UGC NET Commerce Unit 5 PYQs are based on Business Statistics and Research Methods, which is a very important section for Paper 2. This unit includes key topics such as hypothesis testing, sampling methods, correlation, skewness, central tendency, research design, and data interpretation. 

Previous-year questions from this unit help students understand the exam pattern, improve analytical thinking, and strengthen their ability to solve statistical problems accurately. Practicing Unit 5 PYQs regularly is essential for building conceptual clarity and scoring well in the UGC NET Commerce exam.

UGC NET Commerce Unit 5 PYQs

Below are the UGC NET Commerce Unit 5 PYQs that help students understand important concepts of Business Statistics and improve their exam preparation through practice.

Q1. Statement (I): If the alternative hypothesis is as Hα : μ ≠ μ₀, a researcher requires two-tailed test in hypothesis testing.

Statement (II): The mean of the sampling distribution of mean is not equal to the parametric value of mean.

(A) Both the statements are true.
(B) Both the statements are false.
(C) Statement (I) is true, while statement (II) is false.
(D) Statement (I) is false, while statement (II) is true.

Answer:  C

Q2. Read the following statements and choose the correct code:

Statement – I: In statistical hypothesis testing, the null hypothesis states that there is a difference between population parameter and sample statistic.

Statement – II: The two-tailed test in hypothesis testing is a non-directional test.

(A) Both the statements are true.
(B) Both the statements are false.
(C) Statement – I is true while Statement – II is false.

(A) Experimental
(B) Exploratory
(C) Diagnostic
(D) Descriptive

Answer: (A) Experimental 

Q4. Read the following statements and choose the correct code:

Statement – I: When the null hypothesis is true but, according to hypothesis testing, it is rejected, it is known as a beta (Type II) error in hypothesis testing.

Statement – II: Chi-square test is exclusively a non-parametric test.

(A) Both the statements are true.

Answer: (D) 

Q5. Which one of the following statements is the correct interpretation of P-value of less than 0.01 in hypothesis testing?

(A) There is overwhelming evidence to infer that the alternative hypothesis is true.
(B) There is strong evidence to infer that the alternative hypothesis is true.
(C) There is weak evidence to indicate that the alternative hypothesis is true.
(D) There is no evidence to infer that the alternative hypothesis is true.

Answer: (A) There is overwhelming evidence to infer that the alternative hypothesis is true.
