CompTIA Data+ (DA0-001) — Question 342

A director wants a data set that can be used to visualize how various marketing campaigns have performed. The information will be provided by internal and external sources and then compiled to produce the desired data set. Which of the following data techniques should an analyst use to fulfill this request?

Answer options

• A. Appending
• B. Imputing
• C. Blending
• D. Merging

Correct answer: C

Explanation

Blending is the correct answer because it allows for the integration of data from different sources, making it suitable for combining internal and external information. Appending is not appropriate as it refers to adding more data to an existing set without combining different sources. Imputing deals with filling in missing values, which is not relevant to this request. Merging typically involves joining two data sets based on a common field, which may not effectively address the need for diverse sources.
