Question

Directions in Degrees Standard navigation systems used for aviation and boating are based on directions measured in degrees, with north represented by 0° Relative to north, east is 90°, south is 180°, and west is 270°. What is the level of measurement of such directions measured in degrees?

Accepted Answer

Hello, everyone. Let's take a look at this question together, which says time in a 12 hour clock system, and it says standard timekeeping in many countries follows a 12 hour clock system where time is measured using hours from 1 to 12. After 12, the cycle repeats, distinguishing between AM and PM. For example, 30 a.m. and 3 p.m. represent different times, but use the same hour value. What is the level of measurement of hours in a 12 hour clock system? Is it answer choice A, nominal, answer choice B, ordinal, answer choice C, interval, or answer choice D ratio. So in order to solve this question, we have to recall what each of the following terms refers to to determine what is the level of measurement of hours in a 12 hour clock system. Well, we know that the 4 levels of measurement. Are nominal ordinal interval and ratio where nominal is the level of measurement that categorizes data without any inherent order, such as colors or names, we know that ordinal is the level of measurement that represents data with a meaningful order but without consistent differences between. Values such as rankings, we know that interval is the level of measurement that represents ordered data with meaningful differences between values but without a true zero, such as temperature in Celsius. And lastly, we know that ratio is the level of measurement that contains all properties of interval data and has a true. 0, such as height and weight. So now that we have recalled the 4 levels of measurement, we need to determine which of the following levels best represents the hours in a 12-hour clock system. And we know that in a 12 hour clock system, the values are numeric and ordered as the hours continue from 1 to 2 all the way through 12. We also know that the differences between consecutive hours is consistent. Such as the difference between 2 and 3 o'clock is the same as between 5 and 6 o'clock, we also know there is no true zero as 120 a.m. and 120 p.m. do not represent the absence of time. And lastly, we know that the system is cyclical, as 12 follows 11 and resets. rather than continuing indefinitely. Therefore, considering the characteristics of a 12-hour clock system, we know that the differences between values are meaningful. However, the system lacks a true zero, and it cycles back, which tells us that the level of measurement of hours in a 12-hour. The clock system is answer choice C as answer choice C interval is the level of measurement that represents order data with meaningful differences between the values, but it lacks a true zero. So answer choice C is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
