R programming is an open source software programming available for data analyst and researchers. 23 years back it was developed by John Chambers and it was called as S Programming. Later this was developed by Ross Ihaka and Robert Gentleman and was named as R Programming. By the year 2000, a stable version of R got released. It is now developed by R development core team.

Decisions in real life

For the last two years, I have spent part of my time in reading about how humans make decisions. I have bought books like Predictably Irrational by Dan Ariely, Thinking Fast and Slow by Daniel Kahneman, The Art of Thinking Clearly by Rolf Dobelli, Nudge by Richard Thaler and Cass Sunstien, Misbehaving by Richard Thaler and Decisive by Chip and Dan Heath. I’m yet to read Misbehaving and Decisive. I just thought to share what I have learned from the books.

Humans are thinking that they are taking rational decision in their life. Rationality is actually questioned by the books that I have mentioned above. Given a choice (imagine you are dieting), would you like to consume chocolate cake (your favorite one) or raw vegetables. You can pick only one out that. What will you choose? Both are available at free of cost. Will you pick up veggies or will you prefer chocolate cake?. Think about it. I don’t really know what you are going to pick up. Yet this is what you really face everyday, you want to work hard and reduce your weight and get fit. Continue reading

Tips for blog writing

Blogging is a hobby for many and there are few people who take it up seriously as a business and do it. Few even rely for their daily bread by blogging day and night. I maintain this blog for around three years and out my experience I would like to share few tips on blogging. If your intention is to improve the statistics page of your blog then I hope the tips I share will help you. 

Tip 1 # Write more: I have seen my statistics drop down when I don’t write regularly. When I started to read how the search engine works, I found it depends on keywords, links in the website and freshness of the content. Keywords and links do have a major role. Let’s talk about it later on. Google crawlers normally finds the webpage that has a fresh content, hence write more to get more views. Continue reading

Neuromarketing – An Introduction

An emerging field in India and explored field in western countries. Neuromarketing is studying the consumers brain rather than asking questions through a survey. The term was coined by “Ale Smidts” in the year 2002, the research works started to proliferate from the year 2004. A book titled “Buyology” written by Martin Lindstorm is completely based on Neuromarketing research. Neuromarketing research explores the brain of the consumers to capture their unconscious brain. Researchers were able to find that humans are taking most of their decisions irrationally rather than rationality. Irrational thinking happens due to emotional response and unconscious brain. To understand better, when you were learning to ride a bike every part of your body was consciously working to control the bike and think about your situation now you are controlling the bike unconsciously. Even when you are buying a product you do the same, while choosing a product you are not using your rational brain instead your irrational brain (emotional) works better. To understand a conscious brain it’s easy, but to understand the unconscious brain it’s tough so researchers took the help from neuroscience. And that’s why neuromarketing is important. Neuromarketing Continue reading

Google Glass – A Case Study

Google Inc was found by Larry Page and Sergey Brin while they were pursuing their PhD in Stanford University. Google was incorporated on September 4, 1998. Google founders were in the verge to sell its search engine company to Excite CEO George Bell for $ 1 million to continue their doctoral studies. It was unfortunate that George declined the offer, later the company was supported by many venture capitalist companies and Google generated $25 million as the initial investment. After this fund generation Larry Page, Sergey Brin and Eric Schmidt (Executive Chairman) agreed to work together till 2024.

Teaching psychology oriented subject is always interesting. Consumer behavior is one such course that talks more about application of psychology in marketing. “Marketing has moved from products to customers and now to human spirits” as said by Marketing Guru Philip Kotler. Consumer behavioral analysis is inevitable for any marketer. Consumer behavior course kick starts by understanding perception of people towards products and services.

Getting directly into the topic and teaching them core concepts of perception may not interest students, hence I developed a set of activities to make them understand about it. The activities were taken from few websites and thematic appreciation test from SSB interviews conducted for recruiting people in Indian army. I hope even as a reader you might feel really elated to view the pictures posted here.

Illusion is everywhere , and without illusion there is no magic. So start your perception class by showing visual illusion pictures. I have shown these pictures in my class to make it more interesting. First four pictures is related to illusion and the last picture is going to help students in understanding about perception. In the first four pictures ask the same question whatever posted below the picture, students will initially get it wrong and later on they will realize the picture is giving them visual illusions.


Which circle at the center is bigger?


Find out two parallel lines in the picture.


Which line is lengthy?


What do you see here?


Write a story based on this picture.

The last picture is the key. Ask all the students to write a story by looking at the picture ( ensure no one write their name on their story sheet), collect all of them and take only few and read it in the class. It will funny as well as thought provoking. While you read the story you will be able to understand and also the students will understand perception of everyone is different. After doing this activity teaching perception will become easy and you will be able to relate other concepts with the help of the story wrote by students. Perception is a wonderful topic to teach and enjoy teaching it.

First Impression in Interviews

“First Impression is the best impression” is a well know quote to everyone around the globe. When we attend any training to equip ourselves to ace interviews, the trainer will say your first impression plays a major in the selection process. And you know there needs to be a good first impression, but you don’t know what it is all about and why is it so important. This article will let you know the reason behind the saying .

First impression is created by the way you act in the interview in the first 5 – 20 seconds time. In the first instance whether you are showing a broad smile, making eye contact with the interviewer, the words that you use to describe you, and of course your dressing sense is vital in impressing the interviewer.  Continue reading
