- Understanding context
- Big-picture thinking
- Data strategy
- Curiosity
Explanation: The addition of descriptive headings to columns in a spreadsheet is an excellent example of how data may be organized and labeled. In other words, it is the same as giving each item of information its own unique name and location, which makes the data easier to comprehend and more accessible. If you want to conduct an efficient data analysis, organization is the unsung hero!
3. Having a technical mindset is an analytical skill involving what?
- Breaking things down into smaller steps or pieces
- Understanding the condition in which something exists or happens
- Balancing roles and responsibilities
- Managing people, processes, and tools
4. Data design is how you organize information; data strategy is the management of the people, processes, and tools used in data analysis.
- True
- False
Explanation: Absolutely! I couldn't agree with you more. When it comes to data design, the most important thing is to structure and organize information in a manner that makes sense, making sure that it is readily accessible and helpful. When compared to this, data strategy refers to the more comprehensive plan that encompasses the management of the people, procedures, and technologies that are used across the full data analysis lifecycle. It is comparable to having a library that is well-organized (data design) and a strategic plan for how that library functions (data strategy).
5. Correlation is the aspect of analytical thinking that involves figuring out the specifics that help you execute a plan.
- True
- False
Explanation: But it's not quite there yet! In reality, correlation is primarily concerned with determining the ties or connections that exist between different variables or factors. Recognizing that when one thing changes, another item tends to change in a certain manner is the awareness of this phenomenon. It is not necessary about carrying out a plan, but more about recognizing how the many components are connected to one another. There is a possibility that the portion of analytical thinking that includes determining particulars for the purpose of carrying out a plan is more in line with thinking that is focused on accuracy or details. Ensure that your analytical gears continue to spin!
6. What method involves asking numerous questions in order to get to the root cause of a problem?
- Curiosity
- Inquiry
- The Five whys
- Strategizing
Explanation: It is common practice to refer to the methodology known as the "Five Whys" technique. This strategy entails asking a number of questions in order to determine the underlying reason of an issue. You keep asking "why" many times (typically about five times) in order to dig down and uncover the underlying source of a problem. This is a simple strategy that is quite effective. The process is analogous to removing the layers of an onion in order to get to the root of the issue.
7. An airport wants to make its luggage-handling process faster and simpler for travelers. A data analyst examines and evaluates how the process works currently in order to achieve the goal of a more efficient process. What methodology do they use?
- Strategy
- Data visualization
- The five whys

10. Data analysts ask, “Why?” five times in order to get to the root cause of a problem.
- True
- False
Explanation: Absolutely! There is a strategy known as the "Five Whys" methodology, which involves asking the question "Why?" many times (usually five times) in order to probe deeper into the underlying cause of an issue. It is similar to removing the layers of a problem in order to discover the basic root of the problem. The question "Why?" should be asked numerous times in order to discover not just the symptoms of a problem but also the underlying causes of the issue.

13. Identifying the motivation behind data collection and gathering additional information are examples of which analytical skill?
- A technical mindset
- Data strategy
- Data design
- Understanding context
Explanation: In order to demonstrate an awareness of context, some examples include determining the objective of the data collection process and collecting extra information. It entails going beyond the data itself and gaining a knowledge of the larger environment in which the data is acquired. This ability assists in the process of making judgments and interpretations that are guided by a greater grasp of the circumstance or issue that is currently being faced. Remain committed to peeling back the layers of context!
14. Fill in the blank: _____ involves the ability to break things down into smaller steps or pieces and work with them in an orderly and logical way.
- A technical mindset

19. A data analyst works for an appliance manufacturer. Last year, the company’s profits were down. Lower profits can be a result of fewer people buying appliances, higher costs to make appliances, or a combination of both. The analyst recognizes that those are big issues to solve, so they break down the problems into smaller pieces to analyze them in an orderly way. Which analytical skill are they using?
- A technical mindset
- Data strategy
- Understanding context
- Curiosity
Explanation: It seems as if the data analyst is using the skill of issue decomposition in this situation. The broader problem of lesser earnings may be broken down into smaller, more manageable components (such as fewer sales and greater manufacturing expenses), which allows them to conduct a more thorough analysis of each individual facet of the problem. It is similar to taking on one component at a time in order to have a better understanding of the total issue and to handle it.
