Consider a scenario at an online streaming service, where the management has noticed an unexpected fluctuation in viewer engagement metrics.
The data science team has been tasked with conducting a Root Cause Analysis. They begin with Exploratory Data Analysis (EDA) to guide their investigation.
Match the following tasks with whether they are likely part of the EDA phase or subsequent RCA phases:
- Task I: Creating various visualizations of engagement data by time of day, type of content, and viewer demographics to identify any obvious patterns or anomalies.
- Task II: Conducting a detailed analysis of viewer drop-off rates during specific shows to hypothesize about content engagement.
- Task III: Implementing statistical tests to determine if changes in viewer engagement are statistically significant.
Choose the combination that accurately identifies the tasks associated with the EDA phase.
