Quantitative

Analysis for Management,

Chapter 1 Introduction to Quantitative Analysisalsetrue false

1) Interviews, statistical sampling, and

company reports provide input data for quantitative analysis models.

2) In the early 1900s, Henry Ford

pioneered the principles of the scientific approach to management.

3) Managers do not need to be familiar

with the limitations, assumptions, and/or specific applicability of the

quantitative analysis technique to use it for accurate decision making.

4) During World War II, many new

scientific and quantitative techniques were developed to assist the military,

and these developments were so successful that many companies started using

similar techniques in managerial decision making and planning after the war.

5) Business Analytics is a data-driven

approach to decision making that allows companies to make better decisions.

6) Descriptive Analytics is aimed at

forecasting future outcomes based on patterns in the past data.

7) When a problem is difficult to

quantify, it may be necessary to develop unspecific objectives.

8) The Quantitative Analysis Approach

consists of six steps.

9) A mathematical model shows the

relationship between quantifiable and non-quantifiable information.

10) Decision variables may also be called

parameters.

11) Model variables can be controllable or

uncontrollable.

12) A series of steps or procedures that

are repeated is known as an algorithm.

13) A model is a representation of a

situation.

14) A parameter is a measurable quantity

that may vary or is subject to change.

15) Trying various approaches and picking

the one resulting in the best decision is called incomplete enumeration.

16) All problems can be solved by

considering only the quantitative issues.

17) A profit equation is an example of a

schematic model.

18) Testing the data and model should be

done before the results have been analyzed.

19) Sensitivity analysis helps us estimate

the effect of known and unknown errors in our model.

20) Models can help us analyze a problem

and sell a decision to those who must implement it.

21) A sensitivity analysis allows a

manager to answer the “what if” questions.

22) One problem in using a quantitative

model is that the necessary data may be unavailable.

23) Management support and user

involvement are not essential in the successful implementation of quantitative
