Expert Solution

To determine

Identify the data type as categorical, discrete numerical or continuous numerical and the measurement level as nominal, ordinal, interval or ratio for the given question.

Answer to Problem 34CE

The data type of the question “On a 1 to 5 scale, assess the current job market for your undergraduate major.” is categorical.

The question has ordinal measurement level.

Explanation of Solution

A survey is conducted on MBA students. The given question is, “On a 1 to 5 scale, assess the current job market for your undergraduate major. 1 = Very bad ↔ 5 = Very good”.

Categorical data:

The type of data that naturally take non-numerical values, such as words that can classify or name the data points based on their quality, are called qualitative or categorical data. In order to facilitate the use of statistical methods on categorical data, a commonly used process used is coding, where each value of the categorical variable is coded or represented using a unique number.

Discrete numerical data:

The type of data that can take a countable number of distinct numerical or quantitative values is called a discrete numerical data.

Continuous numerical data:

The type of data that can take an uncountable or infinite number of numerical or quantitative values within any given interval is called a continuous numerical data.

The perception of an MBA student regarding the job market for their undergraduate major simply classifies or categorizes the parent. It does not take any numerical values naturally. Even if there are numerical values, mathematical operations cannot be applied on such values.

Hence, the data type of the question “On a 1 to 5 scale, assess the current job market for your undergraduate major.” is categorical.

Nominal measurement:

Nominal measurement is the most basic form of measurement that names or categorizes or classifies data. It is the weakest and easiest form of measurement.

Ordinal measurement:

Ordinal measurement is the measurement that ranks the data in a logical manner. It can be used when a natural ordering is present in the data to give the relative position of one object with respect to another. Numerical values can be assigned to the orders of the data, even when the data values are not naturally numerical. The properties of nominal measurement are applicable for ordinal measurement.

Interval measurement:

Interval measurement is the measurement that can be applied to data that naturally occur in the numerical form and counting of these values is logical. This scale of measurement does not have a meaningful “zero” value. However, the difference between any two points on the scale is meaningful. The operations of addition and subtraction on this scale are meaningful. The properties of nominal and ordinal measurements are applicable for interval measurement.

Ratio measurement:

Ratio measurement is the strongest form of measurement that can be applied to data that naturally occur in the numerical form and counting of these values is logical. This scale of measurement has a meaningful “zero” value. The operations of addition, subtraction, multiplication and division on this scale are meaningful. The properties of nominal, ordinal and interval measurements are applicable for ratio measurement.

The perception of an MBA student regarding the job market for their undergraduate major can be ordered from high to low or from low to high. Such perceptions can be ranked and assigned numerical values. However, application of mathematical operations is not logical on these values.

Hence, the question “On a 1 to 5 scale, assess the current job market for your undergraduate major.” has ordinal measurement level.

Answer to Problem 34CE

The data type of the question “Which political orientation most nearly fits you?” is categorical.

The question has nominal measurement level.

Explanation of Solution

The given variable is, “Which political orientation most nearly fits you? (1 = Liberal, 2 = Middle-of- Road, 3 = Conservative)”.

The political orientation of a student simply classifies or categorizes the student. It does not take any numerical values naturally.

Hence, the data type of the question “Which political orientation most nearly fits you?” is categorical.

The political orientation of a student classifies or categorizes the student. Even when numbers are assigned to such affiliations, these cannot be ranked in a logical order. Moreover, it is not logical to perform mathematical operations on such numbers.

Hence, the question “Which political orientation most nearly fits you?” has nominal measurement level.

A survey is conducted on MBA students. The given question is, “On a 1 to 5 scale, assess the current job market for your undergraduate major. 1 = Very bad ↔ 5 = Very good”.

Categorical data:

The type of data that naturally take non-numerical values, such as words that can classify or name the data points based on their quality, are called qualitative or categorical data. In order to facilitate the use of statistical methods on categorical data, a commonly used process used is coding, where each value of the categorical variable is coded or represented using a unique number.

Discrete numerical data:

The type of data that can take a countable number of distinct numerical or quantitative values is called a discrete numerical data.

Continuous numerical data:

The type of data that can take an uncountable or infinite number of numerical or quantitative values within any given interval is called a continuous numerical data.

The perception of an MBA student regarding the job market for their undergraduate major simply classifies or categorizes the parent. It does not take any numerical values naturally. Even if there are numerical values, mathematical operations cannot be applied on such values.

Hence, the data type of the question “On a 1 to 5 scale, assess the current job market for your undergraduate major.” is categorical.

Nominal measurement:

Nominal measurement is the most basic form of measurement that names or categorizes or classifies data. It is the weakest and easiest form of measurement.

Ordinal measurement:

Ordinal measurement is the measurement that ranks the data in a logical manner. It can be used when a natural ordering is present in the data to give the relative position of one object with respect to another. Numerical values can be assigned to the orders of the data, even when the data values are not naturally numerical. The properties of nominal measurement are applicable for ordinal measurement.

Interval measurement:

Interval measurement is the measurement that can be applied to data that naturally occur in the numerical form and counting of these values is logical. This scale of measurement does not have a meaningful “zero” value. However, the difference between any two points on the scale is meaningful. The operations of addition and subtraction on this scale are meaningful. The properties of nominal and ordinal measurements are applicable for interval measurement.

Ratio measurement:

Ratio measurement is the strongest form of measurement that can be applied to data that naturally occur in the numerical form and counting of these values is logical. This scale of measurement has a meaningful “zero” value. The operations of addition, subtraction, multiplication and division on this scale are meaningful. The properties of nominal, ordinal and interval measurements are applicable for ratio measurement.

The perception of an MBA student regarding the job market for their undergraduate major can be ordered from high to low or from low to high. Such perceptions can be ranked and assigned numerical values. However, application of mathematical operations is not logical on these values.

Hence, the question “On a 1 to 5 scale, assess the current job market for your undergraduate major.” has ordinal measurement level.

The question has nominal measurement level.

Explanation of Solution

The given variable is, “Which political orientation most nearly fits you? (1 = Liberal, 2 = Middle-of- Road, 3 = Conservative)”.

The political orientation of a student simply classifies or categorizes the student. It does not take any numerical values naturally.

Hence, the data type of the question “Which political orientation most nearly fits you?” is categorical.

The political orientation of a student classifies or categorizes the student. Even when numbers are assigned to such affiliations, these cannot be ranked in a logical order. Moreover, it is not logical to perform mathematical operations on such numbers.
