Textbook Question

Determine whether the data are qualitative or quantitative. Explain your reasoning.
The marital statuses of the employees of a casino

Verified step by step guidance

Identify the type of data being described. In this case, the data represents the marital statuses of employees, such as 'single,' 'married,' 'divorced,' etc.

Understand the definition of qualitative data: Qualitative data describes categories or qualities that cannot be measured numerically. It is often descriptive and non-numerical in nature.

Compare the data to the definition of qualitative data. Since marital status is a category (e.g., 'single,' 'married') and does not involve numerical values, it fits the definition of qualitative data.

Explain why the data is not quantitative. Quantitative data involves numerical measurements or counts, such as height, weight, or number of employees. Marital status does not involve numbers, so it cannot be quantitative.

Conclude that the data is qualitative because it categorizes employees into groups based on their marital status, which is a non-numerical characteristic.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Qualitative Data

Qualitative data refers to non-numeric information that describes characteristics or qualities. It often involves categories or labels, such as marital status, which can include options like single, married, or divorced. This type of data is typically used to understand concepts, opinions, or experiences rather than to measure quantities.

Quantitative Data

Quantitative data consists of numeric values that can be measured and analyzed statistically. This type of data allows for mathematical calculations and comparisons, such as age, salary, or number of employees. It is essential for conducting statistical analyses that require numerical input to derive conclusions.

Data Classification

Data classification involves categorizing data into distinct types, primarily qualitative and quantitative. Understanding this classification is crucial for selecting appropriate statistical methods and analyses. In the context of the question, recognizing that marital status is a qualitative attribute helps in determining the nature of the data being examined.
