VARIOUS METHODS TO JUDGE INFORMAL METHOD

Informal research is a idea of getting a quick feed back of the peoples response to a particular idea or action.
This is asking a various group of people orally about their ideas, seeing their reactions to a particular situation like we can take a example of a pizza store like if we want to increasing the store timings then in a next few days days we will come to know about various comments or about the thinking of the people to that. We will see that customers will also have a great impact on our business. We will come to know about thoughts of the persons who are working in the pizza store. With this we will get a lot of useful information through which we can increase our sales.
The another think which we can do to make informal research helpful to us is that we can interview various people one by one by asking various short questions about a particular topic. We should make it sure that information is free of any kind of bias and that information should be free of any kind of personal concert. we should do this to at-least 25 people and than we should judge their views.
