IBM Data Science Practice Test

Data visualization primarily falls into two categories. Which of the following represents this distinction?

1. Visualization using maps versus charts

2. Exploratory versus explanatory visualization

3. Structured versus unstructured data

4. Small-scale versus large-scale data

The correct answer is: Exploratory versus explanatory visualization

The distinction between exploratory and explanatory visualization is fundamental in data visualization practices. Exploratory visualization is used to analyze datasets and discover insights, allowing users to interactively explore data, identify trends, and generate hypotheses. It emphasizes the data analyst's ability to sift through various data elements, visually querying them to derive new insights. On the other hand, explanatory visualization focuses on communicating specific findings or insights to a target audience, often involving a more polished and narrative-driven approach. This type of visualization is typically aimed at providing a clear and straightforward interpretation of results for decision-makers or stakeholders, guiding them through a narrative backed by the data. Recognizing this distinction is crucial for data scientists and analysts, as it influences how they present their findings and how they interact with data throughout the analysis process. Properly employing these two categories allows for a more informed decision-making process and enhances the overall effectiveness of data communication strategies.
