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.
