Ohio Jennifer Cainas, CPA, DBA, is a clinical professor at the University of South Florida in Tampa and Tracie Miller-Nobles, CPA, is an associate professor of accounting at Austin Community College in Austin, Texas. We use Excel to do our calculations, and all math formulas are given as Excel Spreadsheets, but we do not attempt to cover Excel Macros, Visual Basic, Pivot Tables, or other. Wendy Tietz, CPA, CGMA, Ph.D., is a professor of accounting at Kent State University in Kent. Important: The focus of this course is on math - specifically, data-analysis concepts and methods - not on Excel for its own sake. The next time you teach cost behavior, consider expanding your students' Excel skills by teaching them how to perform a simple linear regression, one of the many options within the Data Analysis function. You can also use Excel to calculate a regression with a formula that uses an exponent for x different from 1, e.g. Click on the Data Tab in Excel and then use the Data Analysis tool to fill in a. These tips include ensuring data quality, checking for assumptions, and using custom charts and visuals to present your findings accurately. Highlight the input ranges and then enter the correct formula for regression. Now that you have the regression results, you can discuss with the students the key pieces of information being displayed, including the coefficients (the intercept representing the fixed costs, and the X variable 1 representing the variable costs) and how to interpret the R square and adjusted R square values. A regular linear regression is calculated (with your data) as: LINEST(B2:B21,A2:A21) which returns a single value, the linear slope (m) according to the formula: which for your data: is: Undocumented trick Number 1. Regression analysis in Excel can be tricky, but several tips and tricks can help you perform better regression analysis and make informed predictions. ![]()
