Appeal to Popularity
Many people believe p is true therefore p is true.
False Cause
A came before B therefore A caused B
Appeal to ignorance
There is no proof that p is true therefore p is false
Hasty Generalization
A and B are linked one or a few times therefore A causes B(or vise versa)
Limited Choice
P is false therefore only Q can be true
Appeal to Emotion
P is associated with a positive emotional response therefore P is true
Personal Attack
I have a problem with the person or group claiming P so P is not true
Circular Reasoning
P is true and P is restated in different ways
Diversion (Red Herring)
P is related to Q and I have an argument concerning Q therefore P is true
Straw Man
I have an argument concerning or distorted version of P therefore I hope you are fooled into concluding I have an argument concerning the real version of P
AND statements
Given two propositions p and q, the statement p and q is called their conjunction. It is true only if p and q are both true.
OR statements in and ex
Inclusive- either or both
Exclusive-one or the other, but not both
Inclusive unless told otherwise
OR Statements
Given two propositions p and q, the statement p or q is called their disjunction. In logic, we assume that or is inclusive, so the disjunction is true if either or both propositions are true, and false only if both propositions are false.
IF....THEN Statements
A statement of the form if p, then q is called a conditional proposition. Proposition p is called hypothesis and q is called the conclusion. The conditional if p, then q is true in all cases except when p is true and q is false.
Subset
A may be a subset of B or vice versa, meaning that all members of A are also members of B.
Disjoint Sets
A may be disjoint from B meaning that the two sets have no members in common.
Overlapping sets
A and B may be overlapping sets meaning that the two sets share some of the same members.
Categorical Propositions
All S are P; No S are P; Some S are P; Some S are not P
Inductive Reasoning
general to specific
Deductive Reasoning
specific to general
Absolute Change
absolute change=new value-reference value
Relative Change
Absolute change/reference value
Order of Magnitude
estimate specifies only a broad range of values, such as "in the millions"
Random
unpredictable
Systematic
measurement
Absolute Error
measured value-true va
Relative Error
absolute/true error
Accuracy
how close value is to the true value
Precision
more detail
Index Number
simple way to compare measurements made at different times or in different places
Inflation
rises of prices and wages over time
CPI Reported
Monthly
Consumer Price Index
represents an average of prices in a sample of more than 60,000 goods, services, and households
Rate of Inflation
relative change in CPI from one year to the next
Simple Interest
interest is only paid on the principal amount
Compound Interest
interest is paid both on the original principal and all the interest that has been added to the original principal
Prorate an Expense montly
divide the total expense into 12 months
4 Major Steps to making a budget
