Question
A data analyst has generated insights on customer
retention trends. To effectively communicate these insights, which of the following techniques would be most appropriate?Solution
An interactive dashboard is an effective tool for presenting complex insights like customer retention trends. Dashboards enable data analysts to visually organize data and offer interactive elements that allow stakeholders to explore various aspects of the insights themselves. For customer retention trends, an interactive dashboard can display multiple metrics, trends, and filters, empowering stakeholders to make data-informed decisions quickly. This approach is especially beneficial in a business setting where decision-makers need comprehensive yet user-friendly access to ongoing data trends. The other options are incorrect because: • Scatter Plot may show relationships but lacks comprehensive interactive elements. • Pie Chart is limited to proportions, unsuitable for detailed trend insights. • Box Plot is primarily for distribution analysis, not suitable for trend insights. • Histogram is useful for frequency distribution, not for dynamic trend exploration.
