Excel's Scenario Manager allows you to create named scenarios with different values for key variables. These scenarios can be quickly examined and summarized using the What-If Analysis tool. In this course, you'll use GoalSeek and Solver, both of which are mathematical tools. Goal Seek comes in handy when solving quadratic, cubic, or other equations. Solver is much more powerful and allows complex constrained optimization problems to be easily defined and addressed. As you'll recognize, Solver's interface, used for specifying objective functions and constraints, is intuitive and easy to use. Next, you'll use several heavy-duty statistical techniques in Analysis ToolPak. These range from the creation of correlation and covariance matrices, hypothesis testing, and F-test and T-test interpretations to ANOVA, random and periodic sampling, and the construction and analysis of linear regression models.
WHAT YOU WILL LEARN
-
Discover the key concepts covered in this courseUse the what-if analysis feature in excel, create scenarios based on specific cell values, assign names to these scenarios, and toggle between them, summarize a range of outcomes across scenarios by performing what-if analysis, and interpret the returned resultsUse goal seek for solving simple univariate optimization problems, such as solving univariate equations where a target output cell must be set to a specific value by changing a single input cellEnable the solver add-in and use it to perform complex multi-variable optimization, specify objective functions to min/max or specific values, and specify non-negativity conditions and solution methods for contraintsPerform simple statistical analysis of two-dimensional data, compute measures of central tendency (mean, median, mode) and dispersion (standard deviation and variance), define bessel's correction, and calculate skew and kurtosisEnable analysis toolpak and use it to compute correlation and covariance matrices, interpret the results, and recognize the link between covariance and variance
