- 5. What is it? • Microsoft Add-in for Statistical (Support from Excel 97) • If you need to develop complex statistical or engineering analyses, you can save steps and time by using the Analysis ToolPak. You provide the data and parameters for each analysis, and the tool uses the appropriate statistical or engineering macro functions to calculate and display the results in an output table. Some tools generate charts in addition to output tables.
- 7. Why using it instead of SPSS and MiniTab? • Free • Pre-installed in Excel (from Excel 97) • No need to install third-party software • Light-weight • Interact with Excel directly

- 10. Definition Descriptive statistics are brief descriptive coefficients that summarize a given data set, which can be either a representation of the entire or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread). Measures of central tendency include the mean, median, and mode. Measures of variability include the standard deviation, variance, the minimum and maximum variables, and the kurtosis and skewness.

- 14. Definition Regression is a statistical measure used in finance, investing and other disciplines that attempts to determine the strength of the relationship between one dependent variable (usually denoted by Y) and a series of other changing variables (known as independent variables). Regression helps investment and financial managers to value assets and understand the relationships between variables, such as commodity prices and the stocks of businesses dealing in those commodities. https://www.investopedia.com/terms/r/regression.asp

- 23. What is it? • Microsoft Add-in for What-If analysis (Support from Excel 2007) • Use Solver to find an optimal (maximum or minimum) value for a formula in one cell — called the objective cell — subject to constraints, or limits, on the values of other formula cells on a worksheet. Solver works with a group of cells, called decision variables or simply variable cells that are used in computing the formulas in the objective and constraint cells. Solver adjusts the values in the decision variable cells to satisfy the limits on constraint cells and produce the result you want for the objective cell.
- 24. Parameters of Solver • Target Cell (Objective) • Changing cells • Constraints
- 25. Example of Solver • Target Cell (Objective): Profit from Xbox and Games • Type: Maximize • Changing cells: Console and games price • Constraints: Keep price close to competitor’s price.
