In order to learn about the breakfast habits and preferences of the general population. We suggested using either the convenience sampling, or snowball sampling. Convenience sampling can be done easily where the researches selects respondents who are close by and available for research, they are selected because it is convenient to conduct research with them. While this method is highly easy to follow and implement, one of its biggest drawbacks is that it may present an outcome that is not representative of the actual target audience’s behavior.

### Another method which can be utilized is snowball sampling which has gained popularity over the past years.

It has two stages, the first stage requires the identification of relevant people with the required characteristics.  Who are then interviewed to gain insight. The feedback gained from these people.  Is used to identify other people who can and will be relevant to the research, and are them added in the sample. The second stage primarily involves observing and interviewing the people identified in the first stage, and the same process continues, hence the name, snowball sampling, which starts small and gains momentum as it rolls down the hill, all the while getting bigger and bigger.

The second method, i.e. snowball sampling will be far more effective for the cereal manufacturer because it involves both observational as well as the interviewing technique which can lead to a lot of insights and behavioral habits identified throughout this process. It is most effective for deviant studies as well as subcultures, and behavioral studies.
