Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Types of movies (drama, comedy, adventure, documentary, etc.)

A. Nominal

B. Ordinal

C. Interval

D. Ratio

A. Nominal

Someone is trying to figure out how many hours a day they sleep in a week. The following seven numbers are the hours each day- what is the mean?   6,8,7,10,8,4,9

The sum of those values is 52. There are seven responses, so N=7. You divide the value sum of 52 by N, or 7, to find M, which in this instance is 7.3.

Is this normal distribution, positively skewed, or negatively skewed? 


Normal distribution

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Hair color

A. Nominal

B. Ordinal
C. Interval

D. Ratio

A. Nominal

Explanation
Hair color is a categorical variable that represents different categories or groups. It does not have any inherent order or numerical value associated with it. Therefore, hair color is an example of nominal level of measurement, where data is categorized into distinct groups without any quantitative value assigned to them.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Evaluations of service received at a restaurant (very poor, poor, good, very good)

A. Nominal

B. Ordinal

C. Interval

D. Ratio

  • B. Ordinal

    Explanation
    The evaluations of service received at a restaurant (very poor, poor, good, very good) can be categorized as ordinal level of measurement. This is because the responses can be ranked or ordered based on their quality, indicating a clear hierarchy. However, the intervals between the categories are not equal, and there is no true zero point.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. The amount of calories in a biscuit

A. Nominal

B. Ordinal

C. Interval

D. Ratio

  • Correct Answer
    D. Ratio

    Explanation
    The amount of calories in a biscuit can be measured on a ratio scale. Ratio level of measurement is the highest level of measurement as it possesses all the characteristics of the other levels of measurement (nominal, ordinal, and interval) along with a true zero point. In this case, the amount of calories can be quantitatively measured, and a zero calorie biscuit is possible. Therefore, it falls under the ratio level of measurement.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. The temperature in this room.

A. Nominal

B. Ordinal

C. Interval

D. Ratio

  • C. Interval

    Explanation
    The temperature in this room is an example of interval measurement because it represents a continuous scale where the intervals between values are equal. In this case, temperature can be measured using a scale such as Celsius or Fahrenheit, where the difference between 10 and 20 degrees is the same as the difference between 20 and 30 degrees.
