Final answer:
The main concern with the wealth of big data for marketers is the analytics—interpreting the data correctly. This skill is vital across various sectors and aligns with public concern over data use by companies and governments. Option C is correct.
Step-by-step explanation:
With the wealth of big data available for marketers, the main concern is not the collecting of data, its storage, or the methods of gathering it, but rather the analytics—that is, being able to properly understand and interpret the data. In an era where large volumes of data can be overwhelming, the ability to effectively analyze this data to reach informed conclusions is critical. This skill is applicable in many sectors of society, including understanding consumer preferences, voter behavior, or real estate pricing.
For example, having data on consumer preferences for various bread brands requires analysis to determine whether consumers prefer brand X over brand Y. This analytical skill is becoming increasingly essential in the modern workforce. Notably, a significant portion of the population expresses concern over the use of their data by companies and governments—79 percent for companies and 64 percent for governments—highlighting the need for responsible data management and analysis.
