What it means: This thought conveys the problem of availability bias that data practitioners suffer from. This quote has a World War 2 reference, where many Allied aircraft were lost in fighting with the Axis powers. The question was to up the armor of the correct amount and identify the appropriate place on an airplane to make it more maneuverable and light.
The image below is of an aircraft used by the Allied forces that made it back to the bases. The red dots indicate the places where the aircraft had bullet holes. Now ask yourself, where would you put the additional armor?
You might be tempted to say that the armor should be put on the rudder, around the cockpit, and tips of the wings, i.e., where there are bullet holes. However, according to the Hungarian mathematician Abraham Wald, the additional armor should be put where no bullet holes exist. This is because the aircraft that got hit in the other places, such as the engine, cockpit, flaps, and tail, never made it back alive.
This is an essential lesson on how you should practice data science . Often whole projects are built around the available data, which leads you to ignore the questions whose answers are unavailable in the currently accessible data, causing you to commit availability bias.
Statistics and Predictive models are an integral part of Data Science. The following two quotes provide an essential fact about them.
What it means: When creating predictive models, you should remember that no model can be entirely correct; however, their limited accuracy does not make them obsolete. In your career in data science, you will create several models, and while they will be flawed, only some will be able to solve complex business problems.
What it means: This quote indicates the place statistics has in the field of Data Science. To understand this quote, you need to know of another quote by Mark Twain, who critiqued statistics by saying there are three types of lies – ‘lies, damned lies, and statistics’.
Twain highlighted how applied statistics could strengthen weak arguments and manipulate facts to the extent that they become lies.
Continuing this idea, Andrejs Dunkels, a famous Swedish mathematician, argues that while statistics has its vices and the potential to perpetuate lies, it’s also impossible, to tell the truth without using it. Thus, it would be best if you used statistics very responsibly.

All the quotes you read so far have provided an idea about the nature of data science, its importance, and how it should be practiced. However, like any other discipline, it also has limitations on which the next few quotes will shed light.
What it means: Data Science is a field marred by the practice of manipulation. Statistics is an integral part of data science, and as discussed in the previous quote, statistics can be used for manipulation. This quote underlines the same idea that we can manipulate data (using statistics) to prove a point that we wish to establish, and this is highly unethical.

What it means: Through this quote, you get a fundamental life lesson – no matter your work, it’s useless if it fails to make a difference. A significant limitation of data science is that it can become highly complex.
The insights a data scientist generates can result from using complicated statistics, complex mathematics, sophisticated algorithms, etc.
And if the insights are not properly conveyed to those in the leadership responsible for making big decisions, then all the effort you put into using data science will be futile. This is why reporting and storytelling are crucial aspects of data science.
Being a data scientist is exciting and challenging. Here are some quotes that explain what a data scientist is all about.
What they mean: The above two quotes highlight a data scientist’s unique work. Data scientists need to rely heavily on statistics to make sense of the data at hand; however, they also need to know programming to use their knowledge of statistics.
Also, all the retrieved insights must be put in a business perspective; therefore, they must have good reporting, communication, and business skills. At the same time, these skills are of no use if they lack good analytical skills in the first place.
Without motivation, you’ll stop halfway through and believe you can’t do it when the fault isn’t with you―it’s with the teaching. Take control of your learning by tailoring it to what you want to do, not the other way around – Vik Paruchuri (Founder of Dataquest)
What it means: The founder of Dataquest provided a great quote that every data science aspirant must know, highlighting how the journey of becoming a data scientist is tumultuous. To become a good data scientist, you need a combination of high motivation levels, clear objectives, and an excellent mentor to teach you about this field.
Daniel Tunkelang presented this quote about the work a Data Scientist should do. A scientist retrieves all the initially hidden results and insights from the bulk of data initially.
As the name suggests, Data Science is nothing but the scientific study of data. Therefore you need quotes on data to grasp this field fully.
What it means: This American executive said that without data, any suggestion or decision is just an opinion and encouraged his team to look for data.
What it means: In a way, the CEO of Sara Lee Bakery Group extended the idea mentioned above. He says only God has all the information, so we trust him. To trust anything said by anyone other than God, they must back it up with data, thereby highlighting the importance of it.
What it means: This quote by Jon Acuff explains how data is used in data science. Predictive models in data science are created using historical data with potential predictors and the ground truth. The models we build today try to find the connection between them that allows us to predict events and better prepare us for the future.
What it means: Among the most famous quotes on data is the highly debated quote by this mathematician and marketeer who compared the preciousness of data to oil. The way oil has transformed our new worlds caused massive industrialization and the automobile revolution; data today has the same potential to transform the world.
What it means: You can see this quote in light of the previous one. Countries that have oil have a massive influence on world politics. Similarly, organizations with a lot of data yield massive power as they can create models that often predict human behavior.
What it means: Many data quotes establish the importance of data, but this quote by the famous French priest Ernest Dimnet and writer makes us aware of how great minds are also at the mercy of the available data. Thus if we wish to grow and innovate, we must expand the data quality. This is why former Yahoo president Marissa Mayer emphasizes that when it comes to data collection, ‘the sooner, the better’.
While the quotes so far would have established the importance of data, there are also a few ideas on how to use it effectively.
What it means: Data often indicates the behavior and choices of people. If used efficiently, one can do wonders with it by creating relevant products and pushing the right advertisement to them. However, unlike wine, such contact data gets less valuable as it ages.
What it means: According to Twain, you must clearly know what you intend to do with the data before you collect it. Failing to do so will lead to storing unnecessary data. This idea can be coupled with what K. C. Cole said: If you are aware of your objective, then you can understand the data that might be useless to someone who has no clear objective or needs to learn how to use it.
Rapid digitalization has been a boon for data science as it has led to the phenomenon of big data- a massive amount of data that can hold answers to the most complex problems. The next few quotes focus on the nature and importance of big data.
