Importance of questioning in data analysis.
Constantly asking questions is essential for clarity and insight.
Questions help clarify project plans and resolve conflicts in data interpretations.
Example: "These are the best sandwiches ever, aren't they?"
Leading questions steer responses in a certain direction, limiting unbiased opinions.
Example: "Did you enjoy growing up in Malaysia?"
Closed-ended questions can be answered with yes or no, which limits the depth of insight gained.
Example: "Do you prefer chocolate or vanilla?"
Lack of specificity and context leads to ambiguity in responses (e.g., ice cream vs. coffee flavor).
The ‘ask’ phase is crucial in the data analyst process.
Understanding effective vs. ineffective questioning styles is essential.
Specific questions are focused on a single topic.
Example: Instead of asking about children's physical activities generically, ask, "What percentage of kids achieve the recommended sixty minutes of physical activity at least five days a week?"
Measurable questions can be quantified.
Example: Instead of asking, "Why did a recent video go viral?" ask, "How many times was our video shared in the first week?"
Encourage change and actionable insights.
Example: Instead of asking, "How can we get customers to recycle our product packaging?" ask, "What design features will make our packaging easier to recycle?"
Relevant questions hold significance for the problem at hand.
Example: For a species at risk, a better question would be, "What environmental factors changed in Durham, NC, between 1983 and 02/2004 that could explain the decline of Pine Barrens tree frogs?"
Specify the time frame for data collection.
Example: Focus on the period between 1983 and 02/2004 for environmental questions pertaining to specific species.
Fairness prevents bias in questioning.
Example: Phrasing questions to avoid leading or assuming an answer, such as asking "What do you love most about our exhibits?" which assumes all visitors love the exhibits.
Clear and straightforward wording ensures everyone understands the questions.
Unfair questions lead to unreliable feedback and hinder valuable insights.
Mastering the art of asking the right questions is critical for effective data analysis.
The next phase involves exploring data types and their applications in guiding business decisions, along with the introduction to visualizations and metrics.
