Which of the following statements are true about ‘hypothesis’?

A. The minor premise of the older deductive method was gradually replaced by hypothesis.

B. Snow (1973) described six levels of theory, with the first level being hypothesis formation.

C. For the hypothesis to be testable, the variable must be operationally defined.

D. The most common use of hypothesis is to test whether an existing theory can be used to solve a problem.

E. The hypostasis focuses the investigation on indefinite targets.

Choose the correct answer from the options given below:

Correct option is C

The true statements are:
· B: Snow described six levels of theory, with the first level being hypothesis formation.
· C: For a hypothesis to be testable, the variables must be operationally defined, meaning they should be measurable and clear.
· D: Hypotheses are commonly used to test whether an existing theory can be applied to solve a problem.
Information Booster:
· (a): Incorrect because statement A is not true. The minor premise of the older deductive method was not "replaced" by hypothesis.
· (b): Incorrect because statement E (The hypostasis focuses on indefinite targets) is false. Hypotheses focus on specific, testable phenomena.
Additional Knowledge:
· Hypothesis: A testable statement predicting the relationship between variables.
· Operational Definition: Clear, specific measures of variables in an experiment or study.
· Theory Testing: Hypotheses help to verify or challenge existing theories through experimentation.
