Which of the following is NOT a weakness of using surveys as a research tool?

The assertion that "Data is easy to gain and analyze" reflects a strength of surveys rather than a weakness. Surveys are popular research tools precisely because they can efficiently collect large amounts of data from a variety of respondents. With proper design, the data gathered can often be analyzed quickly through various software tools, allowing researchers to derive insights in a timely manner.

In contrast, the other options highlight common weaknesses associated with surveys. Low response rates can introduce significant bias, making it difficult to generalize findings to a larger population. Additionally, the potential for respondents to provide biased or inaccurate answers can compromise the validity of the results. Lastly, the design process can indeed be time-consuming, requiring careful crafting of questions to ensure clarity and relevance, as well as considerations for the distribution method. All these factors emphasize the challenges that can arise when utilizing surveys effectively for research.
