Identify the type of data​ (qualitative/quantitative) and the level of measurement for the data described below. Explain your ch
ella [17]

Answer:

Option A) Quantitative, because numerical values, found by either measuring or counting, are used to describe the data

Option C) Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.

Step-by-step explanation:

We are given the following in the question:

"The average monthly rainfall in inches for a certain city throughout the year"

Qualitative or​ quantitative:

  • Quantitative data are measures of values or counts and are expressed as numbers.
  • Qualitative data are measures of 'types' and may be represented by a name, symbol, or a number code. They are non-parametric values.

Thus, the given quantitative data is quantitative because rainfall is always measured and the output is expressed in numerical values.

Option A) Quantitative, because numerical values, found by either measuring or counting, are used to describe the data

Level of measurement:

  • Ordinal: These are the qualitative variable whose order plays an important role.
  • Interval: When true zero does not exist. The negative values of such variables make sense.
  • Ratio: When true zero exist. The negative values of such variable does not make any sense.

Since,for the given data true zero exist and a negative values make no sense, thus its is ratio.

Option C) Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.

Answer:

18.7 m/h

Step-by-step explanation:

I believe that is the correct answer because it shows the answer is going to be m/h (meter/hour) so then you would just divide the meters over the hours.

768.57 / 41.1 = 18.7 m/h
