Methodologies used in Calculating people who consume alcohol.
For our research the investigation of people who consume alcohol should be more accurate. Therefor we can withdraw an accurate conclusion with it. When selecting a group of people we should go to large population because there are variations in-between people, they can be ignored when there is a large population in the survey. Survey can be done by considering
• Study population and sampling
• Overall and ethnic specific alcohol use
• Associations of current and hazardous drinking with the level of education, income and occupation
• Smoking and alcohol use
(Dawson, 2003).
Main methodology that is used to investigate the people who consume alcohol is by questionnaires asked verbally. Giving questionnaires written would be a waste because those people show no interest in being participated to such researches. Other methods include aggregate–level analyses for example analysis of mortality rate due to diseases related with long term alcohol consumption or compare variation in per capita alcohol consumption (Dawson, 2003).
