- A new dialog box specific to the selected statistical analysis tool will appear. Configure the options based on your data and analysis requirements. This may include selecting the input range, output range, significance level, dependent/ independent variables, etc. Fill in the necessary fields and click "OK".
- Excel will perform the statistical analysis and display the results in the designated output range or on a new worksheet.
- Review the generated analysis results, which usually include summary statistics, regression coefficients, p-values, etc., depending on the analysis tool used. Interpret and utilize the results accordingly for your research, decision-making, or reporting purposes.
Remember to ensure that your data is organized correctly, checking for things like headers or missing values, before using the Data Analysis ToolPak. The ToolPak is a powerful feature that can enhance your statistical analysis capabilities within Excel.
