Calendar years and time are examples of what scale of measurement?a.Ratiob.Intervalc.Nominald.Ordinal

Breakdown the Problem

1. Identify the characteristics of different scales of measurement: nominal, ordinal, interval, and ratio.
2. Determine which scale best fits the description of calendar years and time.

Relevant Concepts

1. Nominal Scale: This scale categorizes data without any order. Examples include names or labels.
2. Ordinal Scale: This involves order but does not specify the difference between ranks. Examples include rankings in competitions.
3. Interval Scale: This scale measures the difference between values, and while they can be ordered, they do not have a true zero point (like temperature in Celsius).
4. Ratio Scale: This scale has a true zero point and allows for a meaningful comparison of differences. This includes measurements like height, weight, and time.

Analysis and Detail

1. Calendar Years: They are numerical and can be ordered (e.g., the year 2000 comes before 2022), and while you can do arithmetic (subtract to find the difference between years), there is a concept of zero (the year 0).
2. Time: In the context of hours and minutes, it is also a numerical representation that allows for ordering and has a true zero point (00:00 represents the start of the day).

Verify and Summarize

Both calendar years and time possess a true zero point and allow for meaningful comparisons and arithmetic operations, which makes them fit under the ratio scale of measurement.

Final Answer

Both calendar years and time are examples of the ratio scale of measurement (option a).
