- Determine which of the four levels of measurement is most appropriate for the data belowarrow_forwardSelect the measurement scale in the right column that best matches the description in the left column. Note that each scale (nominal scale, ordinal scale, interval scale, and ratio scale) will be used exactly once. The values of data measured on this scale can be rank ordered. In addition, the differences between two adjacent ranks are equal. The values of data measured on this scale can be a number or a name, but they can be rank ordered. The values of data measured on this scale can be rank ordered and have meaningful differences between scale points. For this scale, there is also an absolute zero point. Data on this scale are measured by determining the category to which they belong.arrow_forwardFahrenheit is the measurement of temperature commonly used in the US.

- Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. Internet speed levels of "fast," "medium," and "slow" Choose the correct answer below. O A. The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless. O B. The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point. OC. The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point. O D. The nominal level of measurement is most appropriate because the data cannot be ordered.arrow_forwardDescribe how to calculate/measured each of the following variables using the nominal, ordinal, and ratio scale of measurements.
