Scales of Measurement n n n The scales of measurement describe the nature/properties of data The scale of measurement affects the selection of the test statistic The are four scales of measurement: 1. Nominal 2. Ordinal 3. Interval 4. Ratio

Scales of Measurement: Nominal n 1. 2. 3. Characteristics of Nominal Data: Assigns names to variables based on a particular attribute Divides data into discrete categories No quantitative meaning

Scales of Measurement: Nominal n 1. Example: Gender as a variable Names assigned to variables based on particular attribute -Male or female 2. Divides data into discrete categories -Male or female (not both) 3. No quantitative meaning -Males cannot be quantified as “more or less” than girls

Scales of Measurement: Ordinal n 1. 2. Characteristics of Ordinal Data: Has quantifiable meaning Intervals between values not assumed to be equal

Scales of Measurement: Ordinal n 1. Example: Likert Scales Has quantifiable meaning -”Never” is less than “seldom” -Values can be rank ordered 2. Intervals between values not assumed to be equal ? Never ? Seldom Frequently Always

Scales of Measurement: Ordinal n Other examples: ¨ Small, medium, large sizes ¨ Low, medium, high performance
![Scales of Measurement Interval n 1 2 3 4 5 Characteristics of Interval Data Scales of Measurement: Interval n 1. 2. 3. 4. 5. Characteristics of Interval Data:](https://slidetodoc.com/presentation_image_h2/afdb72fe7f3780728c5027e0965b4d2e/image-8.jpg)
Scales of Measurement: Interval n 1. 2. 3. 4. 5. Characteristics of Interval Data: Has quantifiable meaning Intervals between values are assumed to be equal Zero point does not assume the absence of a value Values do not originate from zero Values cannot be expressed as multiples or fractions
![Scales of Measurement Interval n 1 Example Temperature Fahrenheit or Celcius Has quantifiable meaning Scales of Measurement: Interval n 1.

Scales of Measurement: Interval n 1. Example: Temperature (Fahrenheit or Celcius) Has quantifiable meaning -10 C° is less than 20 C° 2. Intervals between values are assumed to be equal -The difference between 5 and 10 C° = difference between 15 and 20 C° 3. Zero point does not assume the absence of a value -0 C° does not mean absence of temperature 4. Values do not originate from zero -0 C° is arbitrary based on freezing point 5. Values cannot be expressed as multiples or fractions -10 C° is not twice as cold as 5 C°
