Two-Sample Assuming Unequal Variances On Excel Mac 2011 AnswersRefer to the discussion at What happened to the Data Analysis Toolpak or Solver in Excel for Mac 2011 answers.microsoft.com.Quote: The Data Analysis Toolpak was removed in Office for Mac 2008.
Select Tools at the top of your screen and choose Add-ins from the dropdown menu. Two-Sample Assuming Unequal Variances On Excel Install The AnalysisExcel will install the Analysis ToolPak automatically, and you can locate it by clicking the Data tab. Microsofts spreadsheet application known as Excel, found in Microsoft Office, features graphing tools, calculation capabilities, pivot tables and many other helpful tools for its users. In addition to these default features, the user may choose to incorporate various add-ins offered by Microsoft at no cost. The add-in we are discussing today is the Analysis ToolPak which performs complex statistical and engineering analyses. This particular Excel add-in is easy to install and use and saves the user time in performing complex analyses. Because these functions are quite complex and not needed by the average Excel user, they are not found in the default version of the program and it is necessary for the user to add them on his or herself.

The Anova analysis tools (single factor, two-factor with replication, two-factor without replication) provide different types of variance analysis. ![]() ![]() This tool examines a pair or measurement variables and determines whether they tend to move together, or correlate. The Covariance tool can be used in the same setting as Correlation when you have N different measurement variables observed on a set of individuals, and like Correlation, it will give you an output table (matrix) that illustrates the covariance between the two variables. The Descriptive Statistics tool generates a report of univariate statistics for data in the input range, providing information about the central tendency and variability of the data. Exponential Smoothing predicts a value that is based on the forecast for the prior period, adjusted for the error in that prior forecast. It uses the smoothing constant a, the magnitude of which determines how strongly the forecasts respond to errors in the prior forecast.
