Learning
Guide
 Week
11,
Apr
12‐15,
2010
 This
week
we
will
finish
causation
(chapters
14
and
15)
and
briefly
talk
 about
ethical
considerations.

There
is
a
lot
of
material,
but
much
of
it
we
have
seen
 in
various
forms
before.

The
key
question
is
how
does
one
go
from
association
to
 causation
and
what
are
the
assumptions
and
limitations.


In
chapter
14
key
 concepts
are
presented
in
Tables
14‐2,
14‐5
and
14‐6
as
well
as
Figs.
14‐25
and
14‐ 26.

Be
sure
and
visit
the
ELMS
blog
this
week.

You
should
be
able
to
describe
the
 types
of
causal
relationships.

 Chapter
15
deals
with
bias,
confounding
and
interactions.

Be
sure
you
 understand
what
each
refers,
their
relationships
to
each
other
and
their
differences.

 Key
concepts
are
illustrated
in
Tables
15‐2,
15‐7
and
15‐8.

For
interactions
 carefully
work
through
Tables
15‐11
to
15‐16
and
bear
in
mind
the
difference
 between
attributable
risks
and
relative
risks
as
well
as
additive
vs.
multiplicative
 affects.

Think
about
why
real
world
data
often
lies
between
the
two.


You
should
 also
be
able
to
describe
the
concept
of
synergism
and
the
types
of
synergism
as
well
 as
why
it
might
occur.

This
concept
is
often
referred
to
in
biology
as
emergent
 properties
and
these
properties
reflect
not
only
the
contribution
of
each
player
but
 the
contributions
of
the
interactions
between
the
players.


 Chapter
20
is
relatively
short.

Bring
to
class
a
your
own
list
of
ethical
issues
 that
any
study
needs
to
be
concerned
with.



 
 There
will
be
an
in‐class
clicker
quiz
this
week,
on
Wed.
the
15.
