:
A hypothesis is a formal statement of the expected
relationship or relationships between two or more
variables in a specified population. The null hypothesis,
also referred to as a statistical hypothesis, is used for
statistical testing and interpretation of statistical
outcomes. The null hypothesis can be simple or complex
and associative or causal.The null hypothesis states that
there is no relationship between two or more
variables. Extraneous variables exist in all studies and
can affect the measurement of study variables and the
relationships among them. Research objectives or
aims are clear, concise, declarative statements that are
expressed in the present tense, focus on one or two
variables (or concepts), and indicate whether the
variables are to be identified or described. A research
question is a concise, interrogative statement that is
worded in the present tense and includes one or more
variables (or concepts).
