Given the graph below of the probability density function $f\left(x\right)$, which type of data is most appropriately visualized using a probability density function?

• A. Ordinal data
• B. Quantitative data
• C. Nominal data
• D. Qualitative data

Answer: (B)

Verified step by step guidance

1. Understand that a probability density function (PDF) is used to describe the distribution of continuous random variables, which are a type of quantitative data.
2. Recall that quantitative data consists of numerical values that can be measured and ordered, such as height, weight, or temperature.
3. Recognize that ordinal data, nominal data, and qualitative data are categorical types of data, which are better represented by bar charts or pie charts rather than PDFs.
4. Note that PDFs show the likelihood of a continuous variable falling within a particular range, which is not applicable to categorical data types.
5. Conclude that the most appropriate data type for visualization with a probability density function is quantitative data.
