Here's a taster:

Group A: Describing the Data:
·Up to 2 alcoholic drinks a day
causes a decrease in HD risk
·Between 2-3.3 drinks there is an
increase below the original risk level
·Over 3.3 drinks causes an increase
in HD risk
Group B:
·Up to 3 alcoholic drinks a day
causes a decrease in HD risk
·Between 3-4 drinks there is an
increase below the original risk level Age
·Over 4-6 drinks the risk increases A= 21-30
steadily but sure B= 31-40
Group C: C= 41-50
·Up to 4 alcoholic drinks causes a
decrease in HD risk
·Between 4-5.4 drinks there is an
increase below the original risk level These results are showing the correlation
·Over 5.4-6 drinks causes an between the amount of alcoholic drinks a day
increase in HD Risk and the risk of heart disease (HD)…read more

Here's a taster:

Evaluating the Data:
·Does not show that alcohol is a direct
cause of heart disease ­ only a
correlation
·The data suggests that alcohol causes Age
heart disease but we cannot be sure A= 21-30
from this evidence B= 31-40
·You cannot generalise the data C= 41-50
because little information is given
about the research:
·There is no sample size
·There is no information on
sex/gender ·There can be other factors involved with
·There is no information of the alcohol the participants such as:
content in the drinks. This could differ ·Whether they are a smoker ­ because this
the results as some drinks would be is a risk factor for heart disease
equivalent to two. ·Whether they have a diet high in saturated
·There is no information about the fat ­ because this is a risk factor for HD
history of how much the individuals ·The overall health condition of the
have drunk ­ someone with a long individual
history will have a higher risk even if
they drink less nowadays…read more

Explaining the Data:
Age
·Drinking alcohol causes an A= 21-30
increase in blood pressure B= 31-40
·Raised blood pressure is one of C= 41-50
the major risk factors for having
a heart attack or stroke
·Increases in blood pressure can
also be caused by weight gain
from excessive drinking
·There is a lower risk in the younger age group as
·The data does not describe the
the effects of drinking have not affected their
% of the alcohol so we should
body systems ­ but when this does happen it is
estimate at a standard measure
serious
·Elder individuals are able to drink more without
increasing their risk ­ does this suggest that early
lifetime drinking causes damage and it reduced
later in life?…read more
