The Color Red

It is understood that each colour signifies something different, be it emotions or mood. But does colour has any information value? Does colour carry any kind of information to it? I have been pondering upon it, and I think it does, or I might say we know that certain colour means certain things. For example, green means environmental friendly, it also means vegetarian or any thing that is calm. 

But let me put this thought of mine this way; was these meanings made up by humans or do they naturally speak that way. Red means alert isn't it? And this is the colour that I am trying to understand. 

I am going to list certain interpretation, lets see how I go on.

1. Red Blood : It signifies war and all the heinous crime. It also signifies death and all the killing.

2. Red Rose : It signifies love. No other colour could be chosen beside red if you are to purpose a girl. A simple Red Rose will do that.

Isn't it confusing, the same colour seems to speak both the war and peace. But usually it does not confuse us :). We some how know what it means in different conditions. This happens because of its association with other words. 
  
Well be it any thing, I am understanding RED as the colour of information which alerts people. That is why I think all the news channel use it for there themes. Try observing all the news channel and you will see this element in it.

Let me know what you all think of it.

Basic of Population Survey

 Introduction

In any data analysis process, the start of it is the data collection process. Data collection makes all the difference in the result of the analysis. The method of collecting data is also called Sampling Method. There are many methods present which make the process of data collection more efficient and effective.
 
The process is more difficult when we are considering the collection of data for the purpose of measuring the economic parameters like measuring the development of the country. We call it in other words, Population Survey.
 
There are basically two different methods of survey, Cross-Sectional and Longitudinal Surveys. But before, I start explaining these two methods, I want to explain the importance of the sampling.
 
Sampling the Population is a process of choosing particular collections of population from the total population. But this isn't as easy as it seems. It is one of the most difficult tasks of all.
 
Let’s say we have 10,000 people, now if we were to choose 50 people from this population for the purpose of studying the population, what would you do? Obviously, the main target would be to select those particular people who would represent the total population. It's the fundamental problem of sampling? How is that going to be possible, 50 people representing the 10,000 people? Wouldn't it be easy, if it was the whole population or even may be 5,000 of them?
 
But, sampling is done because surveying every individual of the population would not be practically feasible. So what are the methods of attaining the sample?
 
First step, is to understand the total population qualitative and start categorizing them, in terms of
 
1. Religion
2. Demography
3. Age
4. Gender
5. Literacy etc.
 
This kind of analysis gives you the variation in the population and lets you understand the population in qualitative manner. This is very important as it now narrows down the choices of the sample and the sampling method becomes more unbiased. Yes, that is the word, Unbiased Sampling or Random Sampling.
 
Lets take one example to illustrate the Random Sampling:
 
If the sample you take has 80% male and 20% female then you can say the sample is biased. The sample has more male population then female which makes the analysis more male based than female. Therefore, your sample must have no such trends in it that might create a doubt upon the integrity of sample.
 
So now let’s move on to the survey type.
 

Types of Survey

 

Cross-Sectional Survey

 
This is the kind of survey that is taken at a particular instance. This means, the data is collected in order to study the effect of change in one variable to the other variable. This doesn't look at the change with respect to the time. For example, the effect of new advertisement in the sales of that product can only be studied in a particular time.
 

Longitudinal Survey

 
This is the survey to understand the trend in the population.
 

Trend Studies

 
In this kind of study, a particular sample is chosen from a particular population but may not be the same people. The survey is usually carried out over a long period of time. The target would be the variation of certain parameter in a population with respect to time, giving some historical significance.
 

Cohort Studies

 
This is similar to the Trend Studies, except that with the change in time, the sample is always taken from the same population as before. For example, if you sample a 4th grade students and asked them their favorite music genre and then asked the same population after 5 years the same question, when they are in 9th grade, then it will reveal their change in their choice. If instead a new sample of 4th grader were taken after 5 years, it would be Trends analysis.
 

Panel Studies

 
In this study, a sample is choosen and is continuingly queried with in a period of time, tracking them where ever they go. In this analysis, the person in the sample donot change.This method is usually difficult because continuos tracking of the people are necessary.
 

Conclusion

 
So, far, we have understood the type of survey and the importance of unbiased sampling. Always remember that there is no absolute sample or 100% unbiased sample. There is always an approximation in the analysis. Therefore, the next time you see any result from the statistical survey try to understand how the population was sampled; this might help you to understand the analysis better.
 
The above discussion is the basic of any survey and applies to any kind of survey analysis.

The truth is NOT out there, its here.


As I was graduating, my professor use to smile and say ... prepare for the real world. I wondered what he meant by that. I didn't understand this whole concept of the real world. But I think, I know now, as I am in the so called the Real World.

So read my hypothesis and logic that I follow: Please bare with me.
__________________________________________________

No one knows why the hell we are here for. (Everyone knows this, right.)

So scientist, philosophers and all the researchers are searching for it. The Ultimate Answer. Yup, they are given the job of finding answers. There are ways of inciting them to do it. Believe me.

Meanwhile, we all need to exist. And the race must go on. Remember, we still don't have any answers.

Off course to exist, we need to get married and have children. So we have ways of inciting young minds to fall in love and get married. Great.

But, how on earth are Elders or so called Elites of the Society going to answer to all the questions of new generation, coz they are also conscious of themselves. Isn't it?

So here comes the great part or the great ACT........ All the elders then designed a method of answering the questions. They called it EDUCATION. In every Grade, we were told that the lesson from the previous grade is wrong and that what we are reading now is more correct. Damn..

Adding more to it, they kept young minds busy with EXAMS, HONOURS and DEGREES...which really have no purpose......they say.....more degree more answer. Bullshit. :)

So children think...... Ok elders must be right....... Only few break those glasses of rules, after which some get frustrated, while some come out strong and live a life. Hmm.

So the truth is that we all are just making ourselves feel good, about ourselves and living and wondering about this life. Hoping we will have answers to our existence.

Meanwhile, we have Wars that will make us busy, we have disease to worry about, we have Celebrities to look at and laugh at them, we have protest to keep ourself excited. Overall we have us. And yes, we also have Aliens, the other us.

Here, I am trying to come out strong. And I tell about this theory of mine, to my good old pal, and guess what he tells.

He tells me do you know- Quarter Life Crisis.

And I go damm, they even have devised an answer to my reasoning..You see these elders are very SMART. :) Be aware of them.

You see, that is why the Professor smiled at me when he told me this Real World Crap. He knew it. So do I and I smile too. :)

Here: Read this other post that I wrote a long time back. Expectation.

Social Theory in Online Community


Add as a friend, Join the group, Please Donate, Join a cause, Find a Date. Yes, all the things that you can do in the online social network. How interesting and imaginative! 

But, do you think all the classical social theories apply to the online community. I mean does the human behaviour change in the Virtual World or is it the same any way? There are chances that the Virtual Worlds may see a human behaviour that is not seen in the real world. That might be strange. I mean, how can it vary. But the chances are that they will. This can be due to the new possibilities and the moral issues that bind us in the online network.

The geographical barriers are breaking and a new kind of community is taking shape in the clouds and in the electrical database. 

I have only one question. Is this the MATRIX? Do you think that someday, we will be so into the virtual worlds that we will forget that the real world exists and that we may need some kind of saviour to make ourselves conscious of it. Think about it.

Standing Out


How difficult will it be for you to accept the changes in you? How difficult is it to tell yourself that what you are doing is the wrong way and that you were foolish? Yes, its very very difficult. But are you ready to accept it as a fact and live a life, and start fresh.

Is it justified to do so? To change your view on the belief that, what you initially thought was wrong and that now you are hopefully right. Thing is, its difficult to verify what is right and what is wrong. I mean how do you verify that what you are dong is right? My observations are that people tend to look around themselves and see what others are doing. That way they try to tune their life and be in harmony with others. 

Trying to be in pace with others is one key point that contributes to what people think is right and wrong. Your friends, your neighbour, your partners, your colleagues, that is what contributes to your line of thought.

Imagine you alone in this world, what do you think you would do? Get knowledge and be expert or earn money or what do you think you would do. I think you would just wonder and live a life. Just wonder about yourself and live. There would be no aim, no future or career or anything. Just you and your consciousness.

But when you are in a group, you are guided by the need of a group and standing out as an individual in this world is very difficult. You either have to run away and be sage or give up everything and become insane. Sorry for those hard words. But truly, standing as an individual is difficult. 

Try once and you will know.
