The least amount of information is included in nominal scales. A nominal scale is the most basic measurement system we may use to name variables. Variables without quantitative values are labeled using a nominal scale. A nominal scale is a naming scale where variables are merely “named” or l...
The nominal scale is the lowest type on the hierarchy of measurement scales. Consequently, these data provide the most imprecise information because you can only assign labels to the observations. Unlike ordinal data, you can’t even rank nominal data meaningfully—much less perform many of the u...
The Likert scale is a type of rating scale. A rating scale is a measurement instrument used to determine a respondent's attitude toward self, others, or situations. The Likert scale is typically a 5-point scale ranging from strongly agree to strongly disagree. A Likert scale is typically ...
The levels, or scales, of measurement indicate how precisely data is recorded. The higher the level, the more complex the measurement is. The ratio level contains all of the features of the other 3 levels. At the ratio level, values can be categorized, ordered, have equal intervals and ...
The nominal scale is one offourscales of measurement. The other three are: TheOrdinal Scale: Rank order (1st, 2nd 3rd),dichotomous datathat has two choices like true/false or guilty/innocent and non-dichotomous data with choices like “completely agree” “somewhat agree” “neutral” and “...
Survey Research Scales There are four main scales for the measurement of variables: Nominal Scale: A nominal scale associates numbers with variables for mere naming or labeling, and the numbers usually have no other relevance. It is the most basic of the four levels of measurement. Ordinal Scale...

Ordinal scale is the 2nd level of measurement that reports the ranking and ordering of the data without actually establishing the degree of variation between them. Ordinal level of measurement is the second of the four measurement scales. “Ordinal” indicates “order”. Ordinal data is quantitati...
