Question

Determine the level of measurement of the variable.

Time of day measured in military time: 1800, 1900, 2000, 2100, and 2200
Choose the correct answer below:
a. Ratio
b. Nominal
c. Ordinal
d. Interval

Answer 1

Time of day measured in military time is at the interval level of measurement because it can be ordered, and the differences between times are meaningful.

Step-by-step explanation:

In the context of levels of measurement, the variable given as "Time of day measured in military time: 1800, 1900, 2000, 2100, and 2200" corresponds to the interval level of measurement. This is because time in military format has a natural ordering, differences between times can be meaningfully calculated, and although time has zero (0000), it does not represent an absence of the quantity in question (e.g., temperature, where there's a zero point, though it doesn't mean 'no temperature'). Therefore, the correct option for this question is (d) interval.

Answer 2

Answer: Ratio

Step-by-step explanation:

The time of day measured in military time can be considered a ratio variable because it has a clear definition of 0 and the differences between the values are meaningful. For example, the difference between 1800 and 1900 is the same as the difference between 1900 and 2000. In addition, the ratio of any two values can be calculated, such as the ratio of 1800 to 1900. This is not the case for the other levels of measurement, which do not have a clear definition of 0 or allow for the calculation of ratios.
