DA0-001 · Question #74
An analyst needs to conduct a quick analysis. Which of the following is the FIRST step the analyst should perform with the data?
The correct answer is A. Conduct an exploratory analysis and use descriptive statistics. For a quick analysis, the analyst's first step should be to perform an exploratory data analysis (EDA) using descriptive statistics to understand the data's basic characteristics and identify initial patterns or anomalies.

Why each option
For a quick analysis, the analyst's first step should be to perform an exploratory data analysis (EDA) using descriptive statistics to understand the data's basic characteristics and identify initial patterns or anomalies.
Conducting an exploratory analysis with descriptive statistics, such as mean, median, mode, standard deviation, and data distribution, provides immediate insights into the data's structure, quality, and initial patterns, which is crucial before proceeding with more complex analyses. This foundational step helps in understanding the data's nature and formulating further analytical questions efficiently.
Conducting a trend analysis using a scatter chart is a more focused type of analysis typically performed after the initial exploration to examine relationships or changes over time.
Link analysis and illustrating connection points is a specialized analytical technique used for understanding relationships within network data, not a general first step for all quick analyses.
Conducting an initial analysis using a Pareto chart is specific to identifying and prioritizing factors contributing to a problem, which is a subsequent step after understanding the data's fundamental properties.
