FROM “MUCH ADO ABOUT NOTHING”
DOGBERRY “Marry, sir, they have committed false report;
moreover, they have spoken untruths;
secondarily, they are slanders; sixth and
lastly, they have belied a lady; thirdly,
They have verified unjust things; and, to
conclude, they are lying knaves.”
Evaluating Statistics
• Representative• Reliability of sources• Mean (the average)• Median (the middle number)
• According to 2009-10 data collected by USA Today:
• Mean (average) Salary: $ 1,931,518
• Median Salary: $ 812,500
• Lowest: $390,980• Highest: 16+ million
Deploying Statistics
• Identify sources
• Use sparingly
• Round off
• Use visual aids
• Explain your stats:
• interpret
• relate
Examples
•Brief, extended, or hypothetical•Adds Pathos•Strongest impact when vivid and well delivered
•Strongest as evidence when linked with statistics

FINISHED FILES ARE THE RE-
SULT OF YEARS OF SCIENTIF-
IC STUDY COMBINED WITH
THE EXPERIENCE OF YEARS.
Pennies Speech Example• We eliminated the half penny in 1857 without harmful
effect, so we can safely eliminate the penny today.
We can safely eliminate the penny.
We eliminated the half penny in 1857 without harm.
The cases compared are Similar
Reasoning: Analogy
• Reasoning in which a speaker compares two similar cases and infers that what is true for the first case is also true for the second.
• Sample Analogy in Debate

The cases compared are Similar
Reasoning: Analogy
• Figurative• Students are more like oysters than sausages. The job of teaching is not to stuff them and then seal them up, but to help them open and reveal the riches within. (Sydney J. Harris, "What True Education Should Do," 1964)
• Literal• Socialized medicine works in Canada, so socialized medicine will work in the U.S.
Strong or Weak Analogies?
• A ban on all alcohol use in the dorms will work at ISU because such a ban worked at Luther College.
• We praise the lives of soldiers who sacrificed their lives for the sake of others, why can’t we celebrate embryos sacrificed in order to save the lives of others?
Reasoning: Specific Instances
• Moves from particular facts to general conclusions
• Surveys and studies
• Neilson ratings and representative samples
Reasoning: Specific Instances
• UN group proves impact on greenhouse gases
• Humane Society article: 2/3 of ag land for animal support
• Manure from feedlots hurts groundwater
•Meat production hurts the environment
Reasoning: Specific Instances
Meat production hurts the environment
1.impact on greenhouse gases 2. Ag land for animal support3. Manure makes runoff
The generalization is supported (there are enough specific instances; the instances are representative; etc.)
Reasoning: Specific Instances
• my friends and I watched violent cartoons and aren’t violent people, so . . . .
• This is a• Hasty Generalization
Reasoning: Causal Arguments
• The most challenging of the types of reasoning.• We can’t see causal relationships, we can only infer them.
• Examples• “cigarettes cause lung cancer”• “Human beings are causing
global climate change”
Reasoning: Causal Arguments
Serious negative health complications arise.
Over-eating meat leads to obesity.
British Journal of Nutrition; (A happens before B;
A leads to B repeatedly; causal connection makes sense)
Reasoning: Causal Arguments
• Fallacies and Problems• “post hoc ergo propter hoc”
• “after this therefore because of this”• confusing a relationship in time with cause and effect
Reasoning: Causal Arguments
• Fallacies and Problems• multiple causation
• rainforest destruction is the cause of global warming
• T.V. is responsible for school violence
• correlation vs. causation
Tips for success in causal reasoning.
• use causal chains
• use testimony of experts
• combine them with specific instances

“According to a study by the American Medical Association, men with bald spots have three times the risk of heart attack as men with a full head of hair. Strange as it may seem, it looks as if baldness is a cause of heart attacks.”
5. What kind of reasoning is used below? Is it strong or weak? Why?
“Raising a child is just like having a pet—you need to feed it, play with it, train it and everything will be fine.”
