When you think of Mathematics you probably think of it only as a branch of science, It is in fact, also data which is considered as the foundation stone of Science. In fact, the marks you obtained, your weight, the score you get, everything is data. Comprehending the meaning of data, methods, and ways of representing it in the form of graphs is the core component of data handling.
Here are a few real-life examples of data handling –
The data provided is mostly in unorganized or raw form. To arrive at a meaningful conclusion, you need to extract the information efficiently. Let us try to understand with the help of an example –
A group of students was asked for their favorite fruits. The responses were –
Apple, Orange, Mango, Apple, Litchi, Mango, Orange, Litchi, Mango
The process of arranging these data in a meaningful manner to draw proper inferences is called organising data. For example –
FruitsNumber of StudentsApple2Orange2Mango3Litchi2
Often the data provided is large. In such circumstances, data is arranged in a group. For example – Marks obtained by group are as follows- 21, 10, 30, 22, 30, 5, 30, 12, 25, 15, 26
Such representation of data is referred to as grouping data and the frequency obtained is called a grouped frequency distribution.
Pie Chart underscores the relationship between the circle and its parts. The circle is divided into different chunks. The size of every segment is related to the data it represents. In other words, each sector is proportional to the other. It is referred to as a Circle graph because it represents data as a circle.
How many times does it happen that when you take your umbrella with you, it doesn’t rain, and on the off chance that you neglect to take it one day, it rains heavily and you get all wet? There are numerous circumstances that we face in life where we need to take decisions depending on the likelihood of an outcome.
Chance means the happening of any event in the absence of any cause. Probability is one of the cardinal branches of mathematics and an important topic in data. In short, probability means possibility. It is the likelihood of the event to occur.
Probability of an event = Number of outcomes that make an event
Total number of outcomes of the experiment
