What are we doing when we are doing Statistics?

1) We are doing Statistics and we are also collecting Statistics.
2) Why do Social Scientists need Statistics?
The behavior of a society can be quantified in terms of numbers. For example age at marriage of a woman, age of a woman at birth of her first child can be given in terms of numbers. These are indicators of development status of that country. Normally for a developed country these ages are higher than that of a developing country.
3) Why do Doctors need Statistics?
The behavior (well being) of our body can be quantified in terms of numbers. For example a healthy body should have 120/80 mmHg blood pressure, The total cholesterol level is 200 mg/dL or lower. The level of blood sugar for a healthy persons is 4 - 7.8 mmol/L.If blood pressure, total cholesterol and blood sugar are within these levels a person is said to be healthy.
4) Why do Engineers need Statistics?
The strength of a product developed  by an engineering design can be quantified in terms of numbers. For example we can test the breaking strength of a cable produced by a company by exerting force measured in Kilo Newtons. With the help of Statistics we compare the quality of cables produced by two companies.

Everybody asks about statistics. A doctor want's to know about Statistics,  an engineer want's to know about Statistics, a Social  Scientist want's to know about Statistics and  environmental scientist wants to know about Statistics. So what are we actually doing when we are doing Statistics?
1) Statistics means numbers. So talking of statistics means talking of numbers.
2) Statistics also means various statistical methodologies.
3) So we can do statistics implying apply various statistical methodologies.
4) We can also collect statistics implying collect numbers/data related to the objective of study.

Let's conquer the fear of numbers (mathematics)!

The world is flooded with data. We need skills for drawing valuable conclusions from these data. So it is time to learn swimming, surfing, deep diving  and fishing  so that we can make the most out of this flood of data.  
1) To start with this whole process we have to decide about what type of data do we need
2)  Do we need a primary data or a secondary data?
3) If we collect our own data then it is called primary data.
4)  If we use somebody else's data it is called a secondary data.
