The eminent American statistician W. Edwards Deming once quoted;
"Without data, you're just another person with an opinion".
Data provides authenticity and makes the statement more plausible. Let's move on to the big question, what does it mean by data?
What is data?
Before getting an answer to this question, let's take a moment to look at our surroundings.
Our world has billions of people, each of us living in certain countries and states. We can have numerous vehicles, and numerous students are studying in many colleges in many courses. We have many dresses and accessories, and so on.
Here we can see that this are all the information. We can use this information to learn about certain things and also use it to develop the same.
If we collect the information on rural areas, we can find that there only fewer schools and hospitals are available. The government use this information and make a scheme to establish the required necessities in that area.
So this collection and complication of information are known as data.
Data is the complication or set of information about facts and figures.
Now we will see one example to understand this concept clearly.
Rohit bought new dresses for the upcoming Diwali festival. He bought \(5\) new shirts, \(2\) new pants, and \(2\) new shoes. Then he saw his wardrobe he noticed how many dresses he have completely.
The above information is called data.
Now we understand the basic idea about the data; in upcoming lessons, we would cover the classification and different concepts about data.
