Detailed explanation-1: -Hypothesis is an assumption or an idea proposed for the sake of argument so that it can be tested. It is a precise, testable statement of what the researchers predict will be outcome of the study.
Detailed explanation-2: -A hypothesis is a specific, testable prediction or claim about what you expect to observe, given a set of circumstances. A theory is a broader statement used to account for an existing body of knowledge and to also provide unique predictions to extend that body of knowl-edge.
Detailed explanation-3: -A hypothesis is a testable prediction that is arrived at logically from a theory. It is often worded as an if-then statement (e.g., if I study all night, I will get a passing grade on the test). The hypothesis is extremely important because it bridges the gap between the realm of ideas and the real world.
Detailed explanation-4: -DIRECTIONAL HYPOTHESIS. A directional hypothesis is a prediction made by a researcher regarding a positive or negative change, relationship, or difference between two variables of a population.
Detailed explanation-5: -Directional hypothesis: The alternative hypothesis contains the less than (“<“) or greater than (“>”) sign. This indicates that we’re testing whether or not there is a positive or negative effect. Non-directional hypothesis: The alternative hypothesis contains the not equal (“≠”) sign.
