The starting point for his hypothesis was that the dispersion parameter is such that the theoretical proportion above 365 liters annually (that is 100 centiliters
daily) is very small.
* A standard drink is defined as containing 13.6 grams of pure alcohol or 1.72 centiliters
(1cl = 7.91 grams) in Ontario and approximately 11.87 grams or 1.5 centiliters
Binge drinking (heavy drinking occasions) was defined as an occasion when the respondent had consumed at least one bottle of wine, 25 centiliters
of spirits, or four cans of beer.
The frequency of drinking larger amounts was measured by the question: How many times during the last 12 months have you consumed alcoholic beverages corresponding to at least one bottle of wine, 25 centiliters
of spirits, or 4 cans of beer, or more, during one drinking occasion ?
Binge drinking corresponds to drinking one bottle of wine or more in one drinking occasion; one bottle of wine equals 25 centiliters
of spirits or four pints of beer.
The mean consumption has been transformed into 100% alcohol and is displayed as centiliters
The average annual consumption is slightly higher in the younger group (750 centiliters
) than in the older group (736 centiliters
), but the t-test indicates that the difference is not significant (p=.800).
In measuring actual drinking behavior, the researcher defined restrained drinking as being drunk less often than once during the last month and drinking less than 7.5 centiliters
of absolute alcohol on the last occasion.
