- Occurs when participation is not random.
- Can lead to an inaccurate representation of the population.
- Common in voluntary surveys.
Memory trick: Surveys can be skewed, what's left out?
Flaw in Reasoning
Flip cardA flaw in reasoning is an error in the logical structure of an argument that prevents the conclusion from necessarily following from the premises, even if the premises are true.

- Often involves finding an unconsidered variable.
- Suggests the observed effect has a different cause.
- Makes the original conclusion less certain or plausible.
Memory trick: Don't just accept; ask 'What else could it be?'
Weakening an Opponent's Claim
Flip cardTo weaken an opponent's claim means to present information or reasoning that reduces the perceived validity, strength, or relevance of their argument.
- Targets the core premise or conclusion of the opponent's claim.
- Can involve showing the claim is based on faulty assumptions, insufficient evidence, or flawed logic.

Undermining a Claim
Flip cardTo undermine a claim means to present information that directly contradicts its central assertion or significantly weakens the evidence supporting it.
- Directly attacks the claim's validity.
- Often involves showing the premise is false or insufficient.
- Makes the claim less believable or outright disproven.
Memory trick: Undermining is digging away the foundation until the claim collapses.
Undermining Causal Claims (Confounding Variable)
Flip cardTo undermine a causal claim by suggesting an alternative explanation means to identify a third factor that could be responsible for both the presumed cause and the presumed effect, thereby showing the original causal link might be spurious.
- Specifically targets 'X causes Y' conclusions.
- Introduces a 'Z' that causes both 'X' and 'Y'.
- Does not directly refute the correlation, but its causal interpretation.
Memory trick: Two dancers linked by a hidden string, not by their own will.
Challenging a Contention
Flip cardTo challenge a contention means to provide evidence or reasoning that directly opposes or weakens a specific claim or argument made by an opponent.

- Targets a specific statement or premise.
- Does not necessarily refute the entire argument.
- Often involves showing the claim is false, impractical, or has unforeseen negative consequences.
Memory trick: Find the weak point in their specific armor and strike.
Weakening a Specific Counter-Claim
Flip cardTo weaken a specific claim within a counter-argument, provide evidence that directly contradicts or undermines that particular aspect of the opposing viewpoint.
- Pinpoint the exact claim to be weakened.
- Look for data or examples that refute that specific claim.
- Ignore information that addresses other parts of the counter-argument or main argument.
Memory trick: Targeting the weak link in the opposition's chain.
Percentage Change
Flip cardPercentage change describes the relative difference between an old value and a new value, expressed as a percentage of the old value.
- Increase: New Value = Old Value * (1 + percentage increase).
- Decrease: New Value = Old Value * (1 - percentage decrease).
- Percentage changes are applied sequentially, not to the original value if there are multiple changes.
Memory trick: Apply changes one by one, like building blocks on the last result.
Compound Annual Growth
Flip cardCompound annual growth refers to the growth of a quantity over time, where the growth rate is applied to the accumulated amount from previous periods, leading to exponential increase.
- Formula: Future Value = Present Value * (1 + Rate)^Periods.
- The 'rate' must be annual if 'periods' are years.
- Differs from simple interest, which only applies to the initial principal.
Memory trick: Compounding grows like a snowball, adding more to its own mass.
