Question;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;analysis projects.mcq;24) Which of the following terms is;interchangeable with quantitative analysis?;A) management science;B) economics;C) financial analysis;D) statistics;E) None of the above;25) Operations Research is known as;A) the science of numerical analysis.;B) the science of sensitivity analysis.;C) the science of better.;D) the science of modeling.;E) None of the above;26) Who is credited with pioneering the;principles of the scientific approach to management?;A) Adam Smith;B) Henri Fayol;C) John R.
