Rating Scale and it’s characteristics
Definition of rating scale
As per Gibson & Mitchelle – “Rating scales are for rating each of the characteristics or activities one is seeking to observe or assess.”
As per Bonny and Hampleman – “A rating scale is a special kind of checklist in which the items or characteristics checked must be rated quantitatively or qualitatively according to the degree of presence or absence of a trait, the degree of perfection of a skill or a degree of completion of a task.”
Characteristics of rating scale
