Q

Method of argument

A

you find that one factor that is common to all the incidents of all the effects.

Ex:picinic cookout of these 10 people they all had variety of things common all 10 people shrimp cause of the illness is shrimp

23
Q

method of difference.

A

All of the people who didn’t get sick didn’t eat the shrimp.

24
Q

A

put these 2 together

25
Q

method of residues

A

A known effect to suspected cause that can later be confirmed
Ex: loaded vs empty truck

26
Q

Method of concomitant variant

A

as entitles of the courses go up so do the entitles of the effect.

27
Q

Coincidental correlation

A

some unexpected factor is shown to be genuine causes and the corrections is thereby shown to be purely accidental.

Ex: false cause factor
False cause deficient goes up at the same time

An increase in STDS is related to an increase in population. and not more sexual activity same percentage of people are emerging in sex its more of them

28
Q

Joint effect of an underlying cause

A

Some underlying factor is shown to be directly or indirectly responsible for the items correlated. That is the apparent relation of its spurious

Ex: Both effects for changing attitude on sex

29
Q

Genuine but insignificant cause

A

Other factors are shown to be of greater importance in producing the effect in question.
Ex: some people may have sex ed but its insignificant

30
Q

Wrong direction

A

The correlation is shown to support a causal inference in which cause and effect are the opposite of what has been claimed.
Ex: sex education didn’t spike stds the stds spiked the sex education

31
Q

Casual complexity

A

not just the cause there is a collection of causes that produce the effects.
Ex: List of sexual things are the cause
Ex: Drop in the violent crime rate beginning in the late 1990s
Factors - both truths and sentencing laws. Locked up criminals so therefore no criminals
-

32
