Reading the title of this post, I am dead sure that majority of you may be thinking as to what this slim and weird guy means by "BELL CURVE"?. For those of you who are not the student of Marketing, I will take excuse from the ones who knows marketing and would cover up the next few lines of this post with the definition and history of Bell Curve and its resemblance to Marketing.
Everette Rogers , professor of rural sociology, explains in his famous book "Diffusion of Innvoations" about how the purchasing psychology of individual vary from person to person. He says that there are 5 types of categories into which these individual patterns can be captured and segregated,
1. Innovators,
2. Early Adopters,
3. Early Majority,
4. Late Majority and
5. Laggards.
These categories are shown in the picture just beside. This is based on a concept of Mathematics called "BELL CURVE".
