Explanation
★Statements 1, 2 and 3 are correct, so the answer is 1, 2 and 3.
★The Likert scale is a five-point scale of agreement or disagreement with a statement.
★It assumes that the strength of an attitude can be measured empirically.
★It assumes that this strength can be placed along a continuum from strong agreement to strong disagreement.
★Statement 4 is not a valid assumption, because the Likert scale is ordinal, not interval.
★Equal distances between the choices cannot be assumed, since the categories are merely ranked.
★Treating its points as equally spaced is a common misuse of the ordinal scale.
