D265
1. Premise and Conclusion
A manager argues:
“Employees who receive regular training make fewer procedural errors. Our department has
introduced monthly training. Therefore, procedural errors in our department should decrease.”
Which statement is the conclusion?
A. Employees receive regular training
B. Employees make procedural errors
C. The department has monthly training
D. Procedural errors in the department should decrease
Answer: D. Procedural errors in the department should decrease
Rationale: The conclusion is the claim the premises are intended to support. The first three
statements provide supporting information for the prediction.
2. Identifying a Premise
Consider this argument:
“Maria completed three professional accounting courses and received high scores in each. She is
therefore likely to perform well in the company's accounting training program.”
Which is a premise?
A. Maria is likely to perform well
B. Maria completed three professional accounting courses
C. The training program is difficult
D. Maria will definitely succeed
Answer: B. Maria completed three professional accounting courses
Rationale: A premise provides evidence or support for a conclusion. Maria's previous
coursework is evidence used to support the prediction about her performance.
3. Deductive or Inductive?
,“All employees who complete the required certification are authorized to use the system. David
completed the required certification. Therefore, David is authorized to use the system.”
This is best classified as:
A. Inductive
B. Deductive
C. Analogical only
D. An opinion
Answer: B. Deductive
Rationale: The argument applies a general rule to a specific case. If the premises are true, the
conclusion follows necessarily.
4. Inductive Reasoning
A supervisor observes that five employees who participated in a new training program improved
their productivity. She concludes that the training program will probably improve productivity
for other employees.
What type of reasoning is this?
A. Deductive
B. Inductive
C. Circular
D. Contradictory
Answer: B. Inductive
Rationale: The conclusion extends from observations about particular cases to a broader
prediction. The conclusion is probable rather than guaranteed.
5. Validity
Which statement best describes a valid deductive argument?
A. Its conclusion is always factually true
B. Its premises guarantee the conclusion if they are true
C. It must contain statistical evidence
D. It always uses examples from personal experience
Answer: B. Its premises guarantee the conclusion if they are true
Rationale: Validity concerns the logical relationship between premises and conclusion, not
whether the premises themselves are actually true.
6. Invalid Deductive Argument
, Consider:
“All nurses are healthcare professionals. James is a healthcare professional. Therefore, James is a
nurse.”
What is the primary problem?
A. The argument is invalid
B. The argument is inductively strong
C. The conclusion necessarily follows
D. There are no premises
Answer: A. The argument is invalid
Rationale: Being a healthcare professional does not necessarily mean someone is a nurse. The
reasoning reverses the relationship expressed by the first premise.
7. Strong or Weak Induction
A researcher surveys 10,000 randomly selected customers from across the company's national
customer base and finds that 82% prefer online billing. She concludes that most customers
probably prefer online billing.
The argument is best described as:
A. Strong inductive reasoning
B. Invalid deductive reasoning
C. Circular reasoning
D. A false dilemma
Answer: A. Strong inductive reasoning
Rationale: A large, representative sample provides substantial support for an appropriately
limited generalization.
8. Weak Inductive Reasoning
A student asks four friends whether they like a particular restaurant. All four say yes. The student
concludes that nearly everyone in the city likes the restaurant.
What is the main weakness?
A. The sample is likely too small and unrepresentative
B. The argument is necessarily deductive
C. The conclusion repeats the premise
D. The evidence is automatically expert evidence
Answer: A. The sample is likely too small and unrepresentative
