Evaluating Metrics (4 Ways): Positives vs. Negatives:
True Positive = the test says "yes" and the reality is "yes"(ex. the diagnosis says heart attack, and the patient is having a heart attack)
False Positive = the test says "yes" but the reality is "no" (ex. the diagnosis says heart attack, but the patient is actually fine)
True Negative = the test says "no" and the reality is "no" (ex .the diagnosis says no heart attack, and the patient is fine)
False Negative = the test says "no" but the reality is "yes" (ex. the diagnosis says no heart attack, but the patient is actually having a heart attack)
Thought this might be helpful! I know I'm definitely a written/visual learner:
10 FLAWS TO KNOW:
Misdirected Response = when the author or a second speaker responds to an argument the other person never actually made; the response aims for the wrong target
LSAT Answer Ex: "Is directed toward disproving a claim that was not made"
False Dichotomy = when you think you're limited to two options even though there might be other ones available
LSAT Answer Ex: "Assumes without warrant that a situation allows only two possibilities"
Confusing a Mental State with Reality = when you mix up a fact about the world with someone's belief or intention (what's happening in their mind); or the other way around
LSAT Answer Ex: "Assumes that because an action was followed by a change, the action was undertaken for the purpose of bringing about that change"
Confusing a Lack of Support with a False Conclusion = when you think knocking down someone's argument proves that their conclusion is wrong; this is a flaw because the conclusion can still stand, even if you take away it's support
LSAT Answer Ex: "Rejects a position on the grounds that an inadequate argument has been made for it"
Attacking the Source = when you attack the person that holds a view rather than the view itself; whether someone is biased or hypocritical doesn't affect whether their view is true
LSAT Answer Ex: "Attacks the proponent of a claim rather than the merits of the claim"
Overlooking Factors = happens when you base a judgement on only some of the factors that matter; weighing a cost or benefit but ignoring the other side, or fixating on one effect while ignoring the ones that push the other way
LSAT Answer Ex: "Fails to consider that the benefits to be gained might outweigh the costs"
Part vs. Whole = when you assume that something true about individual components of a thing must also be true about the whole thing (or the other way around)
LSAT Answer Ex: "Assumes that because something is true of each of the parts of a whole, it is true of the whole itself"
Unrepresentative Sample = when you generalize about a group based on a slice of it that's skewed in a relevant way
LSAT Answer Ex: "The argument draws a conclusion about a population from observations of a subgroup that is quite likely to be unrepresentative of that population in certain relevant respects"
Assuming Cause From Correlation = happens when you think that the fact two things tend to show up together proves that one thing must have caused the other; there could be other explanations for why the two things show up together (ex. third factor that causes both, or causal direction is reversed)
LSAT Answer Ex: "Illicitly infers a cause from a correlation"
Confusing Sufficient and Necessary Conditions = happens when you think something that guarantees another thing is absolutely required for that thing (or the other way around)
LSAT Answer Ex: "Takes a sufficient condition as a necessary one"
Helpful note about sufficient assumptions that I made for myself:
A sufficient assumption guarantees the conclusion, but it's not necessary because it's not guaranteed by the conclusion
5/5, but absolutely horrible timing (2-4 minutes OVER every question); will this get better with more practice, or should I be working on improving my timing early on? Feel like I should focus more on getting the correct answers before focusing on timing, but this poor timing aspect definitely worries me
Shout out to the odyssey for the context u need for this last paragraph
