A data analyst needs to create a report that anticipates the number of calls received daily. Which of the following is the best statistical method to use?
This question falls under the Data Analysis domain, focusing on statistical methods for forecasting. The task is to anticipate (predict) the number of daily calls, which involves looking into the future.
Predictive (Option A): Predictive analytics uses historical data to forecast future outcomes (e.g., number of calls), which matches the requirement.
Diagnostic (Option B): Diagnostic analytics identifies causes and patterns in historical data, not future predictions.
Inferential (Option C): Inferential statistics make generalizations about a population, not specific forecasts.
Descriptive (Option D): Descriptive analytics summarizes past data, not suitable for anticipating future values.
The DA0-002 Data Analysis domain includes 'applying the appropriate descriptive statistical methods,' and predictive analytics is the best method for forecasting future call volumes.
