Data is an integral part of the modern IT industry, often referred to as the "new oil" for its valuable role in driving business growth. Companies collect vast amounts of data every day from their customers and users, but what is the purpose of all this data?
Data science is the field of study that deals with the extraction of meaning from large amounts of data. A Data Scientist is the professional who applies this science to data. In this article, we will cover:
Now that you have an understanding of what data science is, let's dive deeper and explore its significance through a case study.
Data science is no longer just a future trend, it is already a dominant force in the industry. Companies collect vast amounts of data, and data scientists use advanced techniques to extract valuable insights from it. These insights are used by companies to make important business decisions. To further illustrate the power of data science, let's take a closer look at a real-world case study.
A milk farm located in the city was experiencing steady annual growth in revenue. The owner was dedicated to understanding customer feedback and collected monthly ratings from customers. This was successful for several years, but the owner noticed a sudden decline in the average rating. With a large customer base, it was not feasible to survey every consumer, so the owner asked nearby customers for their input. They reported that they did not have any issues with the milk.
To find the root cause of the problem, the owner sought the help of a Data Scientist. The data scientist analyzed the monthly rating data provided by the owner and noticed that the ratings were significantly lower in July, August, and September. By plotting the data and extracting weather data for the city, the data scientist discovered that the problem was related to the rainy season. However, as the owner had mentioned, nearby customers were satisfied, so the problem was with distant customers.
The data scientist, being an expert in his field, hypothesized that the problem could be related to the containers used to deliver the milk to distant customers. The more the container was exposed to rain, the more likely it was that water would mix with the milk. The owner was able to use this information to make changes to their delivery process, which solved the problem and improved customer satisfaction.
The owner of the milk farm conducted an investigation and found that the data scientist's hypothesis was correct. He made the decision to change the position of the container's opening from the top to the bottom, and sealed it to prevent water from entering. This decision proved to be successful and helped the owner retain thousands of customers.
This case study highlights the importance of data in making strategic decisions. It emphasizes the value of data science, the field of extracting meaning from data, and its growing significance in today's world. Companies worldwide collect various forms of data available online, analyzing and tracking online behavior to provide personalized recommendations.
Companies collect various types of data on our online movements, both with and without our consent. This data can be classified into three categories: structured, unstructured, and semi-structured data.
Understanding the different types of data and how to effectively analyze them is crucial for businesses to extract meaningful insights and make informed decisions.
Companies use various techniques to analyze the data they collect, including:
