  1. what-if analysis,
  2. sensitivity analysis,
  3. goal-seeking analysis, and
  4. optimization analysis
86
Q

user makes changes to variables, or relationships among variables, and observes the resulting changes in the values of other variables.

A

What-If Analysis

87
Q

This type of analysis would be repeated until the manager was satisfied with what
the results revealed about the effects of various possible decisions

A

What-If Analysis

88
Q

A managerial user would be able to observe and evaluate any changes that
occurred to the values in the spreadsheet, especially to a variable such as net
profit after taxes.

A

What-If Analysis

89
Q

To many managers, net profit after taxes is an example of the __________, that is,
a key factor in making many types of decisions.

A

bottom line

90
Q

the value of only one variable is changed repeatedly, and the resulting
changes on other variables are observed

A

Sensitivity Analysis

91
Q

special case of what-if analysis.

A

Sensitivity Analysis

92
Q

a case of what-if analysis that involves
repeated changes to only one variable at a time

A

Sensitivity Analysis

93
Q

decision makers use______________ when they are uncertain about the assumptions made in estimating the value of certain key variables.

A

Sensitivity Analysis

94
Q

reverses the direction of the analysis done in what-if and sensitivity analyses.

A

Goal Seeking Analysis

95
Q

Instead of observing how changes in a variable affect other variables, _________________(also called how-can analysis) sets a target value (goal) for a variable and then repeatedly changes other variables until the target value is achieved

is another important method of decision support.

A

Goal Seeking Analysis

97
Q

is a more complex extension of goal-seeking analysis.

Q

Instead of setting a specific target value for a variable, the goal is to find the
optimum value for one or more target variables, given certain constraints

A

Optimization Analysis

99
Q

Then one or more other variables are changed repeatedly, subject to the specified
constraints, until you discover the best values for the target variables.

A

Optimization Analysis

100
Q
