UGC NET Questions (Paper – 1)

Statements A, B and D describe central functions of hypotheses in research. Hypotheses help focus data collection on relevant variables, indicate suitable statistical tests and often specify the expected direction of relationships. Statement C is false because hypotheses concern propositions to be tested, not established facts, and E is false because explanatory research commonly uses hypotheses to examine causal relations. Thus, the correct combination must include A, B and D while excluding C and E.

Option A:
Option A is incomplete because it excludes D, ignoring the role of hypotheses in indicating whether relationships are expected to be positive, negative or null. Without D, the directional function of hypotheses is missing from the description.

Option B:
Option B is correct because it combines the three statements that accurately characterise how hypotheses guide the design and analysis of research. It recognises that hypotheses are tools for inquiry rather than restatements of facts, and it correctly excludes C and E.

Option C:
Option C is wrong because it retains C, which incorrectly treats hypotheses as established facts, and omits A, which highlights their role in focusing data collection. Including C distorts the provisional nature of hypotheses.

Option D:
Option D is incorrect because it includes E, the statement that hypotheses are meaningless in explanatory research, even though explanatory studies rely heavily on hypothesised relationships. Accepting E contradicts the core logic of hypothesis-testing research.

Explanatory research goes beyond description to investigate why and how certain phenomena occur by testing specific hypotheses about causal relationships among variables. It often uses more rigorous designs such as experiments or sophisticated statistical models to rule out alternative explanations. The goal is to build and confirm theories that explain observed patterns. Because the stem refers to research designed to test hypotheses about cause–effect relationships, explanatory research is the correct term.

Option A:
Exploratory research is conducted when the problem is not clearly defined and the researcher seeks to gain familiarity, generate ideas or identify variables, without strong prior hypotheses about cause and effect. It is thus less focused on hypothesis testing than explanatory research, so it does not fit the stem.

Option B:
Descriptive research aims to present an accurate picture of characteristics, frequencies or distributions of variables, answering “what” questions rather than “why.” It does not primarily test causal hypotheses, so descriptive research is not the right completion here.

Option C:
Explanatory research typically builds on earlier exploratory and descriptive work and requires careful control or statistical adjustment for confounding variables. Its emphasis on causal reasoning and hypothesis testing aligns exactly with the description given in the question.

Option D:
Diagnostic research is oriented toward identifying reasons for specific conditions or problems in applied contexts, such as why a particular programme is failing, but the term is less commonly used as a general label for testing causal hypotheses across variables. Therefore, diagnostic research is not the best answer.

Statements A, B, C and E accurately summarise different research purposes. Descriptive research portrays characteristics, exploratory research clarifies poorly defined problems, and explanatory research tests hypotheses about relationships and causes. Descriptive findings can indeed guide later explanatory work. Statement D is false because historical research does interpret past events; it does not merely list them.

Option A:
Option A is incomplete as it omits E, thereby ignoring how descriptive work often serves as a foundation for more complex causal investigations. Without E, the progression from description to explanation is not fully represented.

Option B:
Option B is correct because it gathers all the true statements about descriptive, exploratory and explanatory research and their interrelationships. It rightly excludes D, which mischaracterises historical research as uninterpreted description. This combination aligns with standard classifications of research purposes.

Option C:
Option C is incorrect because it retains D, the false statement about historical research, and omits A, which properly defines descriptive research. Including D and excluding A distorts the classification of research types.

Option D:
Option D is wrong because it includes D along with other statements, accepting an incorrect view of historical research. By treating D as correct, the option underestimates the interpretive nature of historical inquiry.
