Errors in Spreadsheets Are Common,[object Object],[object Object]
Although comprehensive code inspection is the best protection, simple controls  such as independently checking expected results before accepting spreadsheet output  can reduce errors
Among the most persistent impediments to better controls and design are overconfidence and insufficient time,[object Object]
Spreadsheet Errors,[object Object],The average error rate for all formula cells is slightly less than 10% (Lerch 1988),[object Object],Increasing complexity to spreadsheets leads to increased likelihood of errors,[object Object],References to cells in different rows and columns have the highest incidence of error at 14.1%,[object Object],References to cells in the same row is about 6.4% ,[object Object],References to cells in the same column is about 4.7%,[object Object]
Teamwork,[object Object],Working alone with no design training results in the highest incidence of error at 14% (Janvrin & Morrison 2000),[object Object],Working in pairs can cut that error rate by about half,[object Object],Undergrads demonstrated an interesting exception to the benefit from working in groups ,[object Object],Working in groups of three their error rate increased 30% (Panko 1999),[object Object]
