1.3. Life satisfaction is negatively associated with alcohol use
So, in order to eradicate skewness lograthimic transformation of the dependent variable is used. Figure 3 provides a before transformation frequency distribution (red graph) and after transformation frequency distribution of absence variable (green graph). First is to select list of significant explanatory variables that helps in estimating final grades. Multiple linear regression can be used for this purpose to create an initial model with all the independent variables and then forward selection or backward elimination could be used to find out most significant list of explanatory variables using both AIC & BIC penalties.
Some students may have to obtain a job that can interfere with attending class or study time. Drinking impairs immune cells in the lungs, leading to ailments such as pneumonia and tuberculosis. From the visual inspection of the variable it can be seen that the variable is positively skewed as the number of absences of most of the students were very less.
Social anxiety and alcohol use: Evaluation of the moderating and mediating effects of alcohol expectancies
Evidence shows that white students tents to have three or four more drinkers than a African American students. “The results of the study, which involved a detailed survey of more than 1,100 students, found that on average whites drank alcohol slightly more than four days a month. And when they did drink alcohol, whites were far more likely than blacks to consume a large quantity. When asked how many drinks they had the last time they partied, whites reported an average of 5.39 drinks. Whites reported binge drinking having five or more alcoholic drinks at one sitting 2.61 times per month.” (journal of Blacks in Higher Education, 2004). Secondarily, we examined the relationships between social anxiety and DMs and social anxiety and AOEs in order to examine potential mediators of the relationship between social anxiety and alcohol use or ARPs.
But for females, the results based on self-reported grades showed positive effects of alcohol consumption that were statistically significant at the 10% level for three out of five consumption measures (monthly binging, total drinks per month, and drinks per episode). Furthermore, with the exception of the frequency measure (drinking days per month), the estimated effects were all substantially larger (i.e., more positive) when based on self-reported GPA. This suggests that females who drink more intensively tend to inflate their academic performance in school, even though their actual performance is not significantly different from that of those who drink less.
