Levels of Measurement Indicate the Inferences That Can Be Drawn

The Answer is The four levels of measurement are nominal, ordinal, interval, and ratio.

1. Nominal level: This level of measurement involves categorizing data into distinct groups or labels. Inferences that can be made when comparing units in different variable categories at the nominal level are limited to determining whether the categories are different or the same. For example, if comparing different genders (male and female), the inference that can be made is simply whether the genders are different or the same.

2. Ordinal level: At this level, data is ranked or ordered based on a specific criterion. Inferences that can be made when comparing units in different variable categories at the ordinal level include determining the ranking or order of the categories. For example, if comparing educational levels (e.g., high school, college, graduate school), the inference that can be made is the ranking of these categories from lowest to highest.

3. Interval level: This level of measurement involves data that has a specific order and equal intervals between values, but does not have a true zero point. Inferences that can be made when comparing units in different variable categories at the interval level include determining the numerical difference between the categories. For example, when comparing temperature in Celsius, the inference that can be made is the numerical difference between two temperature values.

4. Ratio level: This level of measurement includes data with a specific order, equal intervals between values, and a true zero point. Inferences that can be made when comparing units in different variable categories at the ratio level include determining the ratio of the values. For example, when comparing income levels, the inference that can be made is the ratio of one income level to another.

In summary, the levels of measurement indicate the types of inferences that can be made when comparing different variable categories, ranging from simply determining whether categories are different or the same at the nominal level, to calculating the ratio of values at the ratio level.
