1.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Types of movies (drama, comedy, adventure, documentary, etc.)
Correct Answer
A. Nominal
Explanation
The types of movies (drama, comedy, adventure, documentary, etc.) can be classified into different categories without any specific order or ranking. Each type of movie is distinct and does not have a numerical value associated with it. Therefore, the most appropriate level of measurement for this data is nominal, which is used for categorical data without any numerical significance or ranking.
2.
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)
Correct Answer
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.
3.
Which level of measurement represents data with categories or labels, but no inherent order or ranking?
Correct Answer
A. Nominal
Explanation
Nominal level of measurement represents data with categories or labels, where there is no inherent order or ranking among the categories. It is the least restrictive level of measurement and is used for data that can be categorized but does not have a meaningful numerical value. Examples include colors, types of animals, or political affiliations.
4.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Amount of proteins in a soup
Correct Answer
D. Ratio
Explanation
The amount of proteins in a soup can be measured on a ratio scale. Ratio level of measurement is the highest level of measurement as it has all the characteristics of the other levels of measurement (nominal, ordinal, and interval) and also includes a true zero point. In this case, the amount of proteins can be measured quantitatively and can have a true zero value (i.e., absence of proteins). Therefore, ratio level of measurement is the most appropriate for determining the amount of proteins in a soup.
5.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Amount of calories in a biscuit
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.
6.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Calendar year
Correct Answer
C. Interval
Explanation
The most appropriate level of measurement for "calendar year" is interval. Interval level of measurement is characterized by equal intervals between values and no true zero point. In the case of calendar year, the intervals between years are equal (e.g., the difference between 2000 and 2001 is the same as the difference between 2010 and 2011), but there is no true zero point (i.e., the year 0 does not exist). Therefore, it falls under the interval level of measurement.
7.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Students’ scores on a biology test
Correct Answer
D. Ratio
Explanation
The most appropriate level of measurement for determining students' scores on a biology test is ratio. Ratio level of measurement includes all the characteristics of the previous levels (nominal, ordinal, and interval) and also has a meaningful zero point. In this case, the scores on the biology test can be measured on a continuous scale, with a clear and meaningful zero point (i.e., a score of zero indicates no knowledge or performance). Therefore, ratio level measurement is the most suitable for this scenario.
8.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. The time it takes to finish an exam.
Correct Answer
D. Ratio
Explanation
The time it takes to finish an exam is measured on a ratio scale. This is because the variable has a meaningful zero point, which represents the absence of time taken to finish the exam. Additionally, the measurements can be compared using ratios, as one can determine if one person took twice as long as another to finish the exam.
9.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. Hair color
Correct Answer
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.
10.
Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is the most appropriate. The temperature in this room.
Correct Answer
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.
