Final answer:
Analysts should consider outliers in the data and the timeline of events before beginning any data analysis.
Step-by-step explanation:
Before any data analysis is begun, it is important for analysts to consider several factors. One factor that is often missed is the careful examination of outliers in the data. Analysts should determine whether an outlier is a result of incorrect data or if it holds valuable information about the population under study. Additionally, analysts should think about the timeline of events and the order in which they occur, as understanding the cause-and-effect relationship is crucial for accurate analysis.
