Study Notes
- Measurement is the process of applying numbers to objects based on set rules, like measuring height using a tape measure.
- In statistics, there are four scales of measurement: nominal, ordinal, interval, and ratio.
- Nominal scale assigns numbers to objects to differentiate them, like assigning 1 to males and 2 to females without any inherent meaning.
- Example of nominal scale includes gender where numbers are used for differentiation, not to imply superiority or inferiority.
- Another example of a nominal scale is baseball uniform numbers which simply distinguish between players.
- Ordinal scale assigns numbers to objects with meaningful order, indicating rank or position like first, second, third place in a race.
- Interval scale, in addition to having order like ordinal, also has equal intervals between adjacent categories, such as temperature in Fahrenheit.
- In an interval scale, the difference between 78 and 79 degrees is the same as between 45 and 46 degrees, showing equal intervals throughout the scale.
