An important aspect of data collection is understanding how the data are to be used. This knowledge influences various elements of the data collection process, including what data is relevant, how it should be gathered, the methodology to apply, and the parameters to focus on. Knowing the intended use of the data ensures that the data collection aligns with project objectives and helps ensure that the right information is captured, which can directly impact the effectiveness and relevancy of any analysis performed later on. This focus leads to more meaningful insights and helps in making informed decisions based on the data collected.

In contrast, while determining the dispersion of the data, analyzing with a control chart, or using a stratified sampling plan are useful techniques in the broader context of data analysis and collection, they are secondary to the fundamental understanding of how the data will be utilized. Each of these methods serves a purpose after understanding the end goals; however, they do not alone justify the data collection framework without a clear understanding of how that data will contribute to achieving the objectives.
