Discussion
Which of the following is a type of hypothesis ?
Answer: D
The type of hypothesis among the options is the null hypothesis.
The null hypothesis (H0) states that there is no difference or no relationship between the variables studied. Statistical tests are designed to reject or fail to reject it, and the alternative hypothesis (H1) states the difference or relationship the researcher expects.
'Zero hypothesis' is a literal rendering of 'null' but is not the term used. Absolute and abstract hypotheses are not recognised types; the usual classifications are null and alternative, directional and non-directional, and descriptive, relational and causal.
