What is an objective function?

A formula that relates the variables to the desired outcome

What is the difference between a linear function and a nonlinear function?

A liner function results when you multiple a decision variable by a constraint, and can be graphed in a straight line. A nonlinear function is a function that cannot be described as linear.

What type of reports can you create for scenarios? Which type shows results only?

A scenario summary and a scenario PivotTable. The scenario PivotTable report shows results only.

What are the advantages and disadvantages of using the Subtotal tool to analyze data?

Advantages are you can create summary reports that combine related data and calculate totals and subtotals. Disadvantages are that it only works with one category and one subtotal calculation at a time.

What is an infeasible solution? What steps can you take to attempt to change an infeasible solution into a feasible solution?

An infeasible solution is a solution that does not satisfy all the constraints. You can attempt to change the solution to be feasible by using a Feasibilty Report to isolate the source of infeasibility.

An unbounded solution is a solution when there are no/too few constraints

What are the types of Solver reports? What information is described in an answer report? What is the difference between a binding status and a not binding status? What is slack?

Answer, sensitivity and limits. An answer report describes the solution in detail. Binding status indicates that the constraint has a final value equal to a value of the constraint. Not binding status is the constraint does not have a final value that is equal to the value of the constraint. Slack is the amount of resource that hasn't been used.

Both HTML and XML are markup languages that used on the web. XML is used to structure, store, and transport data whereas HTML is used to display data.

How do the FIND and SEARCH functions work, and how are they different?

Both functions find one text string within another test string. They are the same except the FIND function is case sensitive, SEARCH is not.

Compare break-even analysis and sensitivity analysis

Break-even analysis concentrates on the point the product's profit is $0, whereas sensitivity analysis concentrates on how sensitive the results of the analysis are to changing assumptions.

Function to calculate the value of a variable set of cash flows discounted to its present value

NPV(rate,value1,[value2],...)

What is the difference between a one-variable data table and a two-variable data table? When would you use each type of data table?

One-variable tables have only one input cell and can have many result cells, and can be used to see how different interest rates affect a loan payment. Two-variable tables have two input cells but only one result cell, and can be used to see how different interest rates and loan terms would affect a loan.

Function to calculate periodic payments into or out of a financial transaction

PMT(rate,nper,pv,[fv],[type])

What is the difference between a policy constraint and physical restraint? Give one example of each type of constraint.

Policy constraint is a constraint based off of the company's past history. Ex. restricting how much a customer can buy at a sale price. Physical constraint is a constraint that has physical limitations. Ex amount of product that can fit on a truck

What are the two advantages of creating a constraints table in a worksheet that includes a Solver model?

Provides record of the constraints and allows for cell reference with the solver.

What is the Query Wizard, and when would you use it?

Query Wizard is a simpler way to use Microsoft Query, which lets you create queries to select data from external sources. You would use it when you only want specific data from a database, instead of all of the data in the database.

What types of what-if question can a simulation answer?

Simulations can answer questions with more than two variables

Why should you remove unnecessary spaces from data imported from another source? How do you remove unnecessary spaces from a text string?

Spaces create errors. Use TRIM function to eliminate these.

Describe how the SUMPRODUCT function works.

Takes one or more arrays or numbers and calculates the sum of products of the corresponding numbers

What is the difference between the LOOKUP function and the VLOOKUP or HLOOKUP functions?

The LOOKUP function can retrieve data from a lookup table with a vertical or horizontal orientation, and only uses TRUE lookup type.

What requirements exist for cells in arrays when you use the SUMPRODUCT function?

The arrays must be identical in size, shape, and orientation.

What is the primary advantage of storing data in a database and importing that data into Excel

The database keeps the data available and protected, and Excel provides analytical power.

Explain how you must vary the setup of a two-variable data table to run a simulation via the table.

The setup must be structured so that the input values are perpendicular to each other and the table's output formula is located at the intersection of the two sets of input variables. One set of input values in the data table's structure must be a sequence of numbers that represents the number of iterations of the situation

True or False? Excel matches the lookup_value "tom" with the entry "TOM" in a lookup table.

True

True or False? In a VLOOKUP formula with a TRUE lookup type, the first column of the lookup table referenced must be in ascending order to retrieve the correct value.

True

True or False? The default range_lookup type for VLOOKUP and HLOOKUP functions is TRUE.

True

True or False? The result_vector of a LOOKUP function must be sorted in ascending order.

True

True or False? The row and column arguments in the INDEX function can be numeric values, Boolean values, or text.

True

How many variable cells can you use in a Solver model?

Up to 200

List and describe the steps you would take to create a structured list of data from a text file that contains values stored on separate lines

Use CONCATENATE function to combine the information from each line into a text string in a single cell. Use functions such as TRIM or PROPER to manipulate data in desired way. Then use Convert Text to Columns Wizard to separate values in the text string into columns. Lastly, add a header row and add labels to identify data in each columns and use Sort tool.

When should you include integer constraints in a Solver model? What is the disadvantage of using an integer constraint?

Use integer constraints when you need a value in the solver model to be shown as a whole number. The disadvantage is that is adds complexity and causes the solver to run slower

When should you use a PivotTable report to analyze data?

When you need to analyze data that can be summerized in multiple ways

When should you create a scenario instead of a data table? Give an example of a business situation that could best be analyzed with scenarios.

When you want to perform a what-if analysis with more than two input cells. Ex. Comparing the results of maintaining the price of a product, offering a discount, or increasing the price.

With a PivotChart, you can change the layout and data displayed by moving fields in addition to changing the chart type
