1. What are the leading causes of Spreadsheet errors?

The leading causes of spreadsheet errors are

a) Human incapability of doing complex cognitive tasks with accuracy, this is a limitation in human capability and this contributes partly to the errors that are caused in spreadsheets

b) Lack of disciplined development practices is one of the most common reasons why spreadsheet contains errors. Many organization has policies in general about end user development in general, much less spreadsheet development

c) Many developers build the models and hardwire it to one end result they are working without considering the constraints or different possible scenarios. This ultimately leads to the fact that the model doesn’t work for any other input variables other than the one that is being used to.

d) Another common reason of spreadsheet errors is due to the overconfidence of the developers in the accuracy of the spreadsheets. They don’t spend time to test the spreadsheet for any possible errors

e) We could also say innocence (in a sense of not knowing the excel capabilities) as one of the common reasons why spreadsheets has errors, people tend to learn from friends and coworkers without any proper training on Excel and its capabilities which ultimately lead in unstructured spreadsheet development

2. Why these errors are typically not detected?

a) Primary reason for missing out these errors is that there is no adoption of the standard development cycle phases, many developers directly jump in and do the development without putting any thoughts and scenarios and once the development is done there is very little or no effort put in to test what is developed with different decision parameters.

b) Secondly since there is no standard…...

...1 Microsoft Excel 2010 Tutorial Excel is a spreadsheet program in the Microsoft Office system. You can use Excel to create and format workbooks (a collection of spreadsheets) in order to analyze data and make more informed business decisions. Specifically, you can use Excel to track data, build models for analyzing data, write formulas to perform calculations on that data, pivot the data in numerous ways, and present data in a variety of professional looking charts. The Ribbon Understanding the Ribbon is a great way to help understand the changes between Microsoft 2003 to Microsoft 2010. The ribbon holds all of the information in previous versions of Microsoft Office in a more visual stream line manner through a series of tabs that include an immense variety of program features. Home Tab This is the most used tab; it incorporates all text and cell formatting features such as font and paragraph changes. The Home Tab also includes basic spreadsheet formatting elements such as text wrap, merging cells and cell style. Insert Tab This tab allows you to insert a variety of items into a document from pictures, clip art, and headers and footers.

Instructions: For the purpose of grading the project you are required to perform the following tasks: Step Instructions Points Possible 1 Start Excel. Download, save, and open the file named Exploring_e05_Grader_EOC.xlsx. 0 2 Sort the data on the Subtotals worksheet first by the Type column, then by the Art column, both in alphabetical order. 4 3 Subtotal the data at each change in Type. Identify the highest issue price, estimated value, and percent increase. 10 4 Add an automatic outline to the Subtotals worksheet. Group the first and last name columns. Collapse the names columns, and then collapse columns created by the outline (G, H, and I). 7 5 Create a PivotTable on a new worksheet using the data on the Christensen worksheet in the range A1:J19. Use the Type, Est. Value, and Issue Price fields and use the default locations in the PivotTable Layout. 8 6 Modify the Issue Price and Est. Value values to determine the average issue price and average estimated market value by type. 6 7 Insert a calculated field named % Change in Value to determine the percent change in values by type.

...P rate and y = T P rate. Possible values range from (0, 0) to (1, 1). The “classiﬁcation” that assigns “Test Negative” to every score has FP rate of 0 and TP rate of 0, represented as point (0, 0). The “classiﬁcation” that assigns “Test Positive” to every value has FP rate of 1 and TP rate of 1, represented as the point (1, 1). Joining all known (x, y) points by straight lines, the area under the resulting empirical ROC curve is known as the Area Under the Curve or AUC. The AUC ranges from 0.5, for a test no better than chance, to 1, for a perfect test. The Area Under the Curve is calculated by the summation of the average height multiplied by the width, as follows: ! ! T P (n) + T P (n + 1) 1 2 (F P (n + 1) F P (n)) See Excel Spreadsheets for examples of calculating each point on an empirical ROC Curve. 2 2.1 2.1.1 Information Measures Probability Review Basic Probability Deﬁnitions Joint probability: p(X, Y ) The probability that both X and Y are true. Joint probability is commutative: p(X, Y ) = p(Y, X). Conditional probability: p(X|Y ) The probability that X is true, given that Y is true. Note that “Rates,” PPV and NPV are Conditional Probabilities: True Positive Rate = p(T P T est|+), 3 False Negative Rate = p(F N T est|+), False Positive Rate = p(F P T est| ), True Negative Rate = p(T N T est| ), Positive Predictive Value = p(+|T est P ositive), Negative Predictive Value = p( |T est N egative).

...Applied Statistics Microsoft Excel Decomposition may reduce appeal emphasis on applications. Flow charts help make the analysis decision by identifying technique, computing statistics, and interpreting results. Associated data set accompanies the set purports to build a excel spreadsheet that discovers formula, illustrates the parameters, observes dynamic graphs and simulations that recodes, edits, validate, charts, and automatically links equations, data, and formulas to recalculate the data analysis. Excel recognizes statistical capability conjunction that carries out complex algorithms that implement correlated data columns. Excel quickly analyzes and interprets information filtered into a spreadsheet so the process is much easier then working out these formulas by hand. Excel spreadsheets create charts, graphs, and filters data all into one. Excel uses all of the basic mathematical operations such as addition, subtraction, division, and multiplication. Fractions and decimals are just as common for interpretation data into a excel spreadsheet. An advantage about excel is you can place any formula into the spreadsheet whether in ascending or descending order and using the same formula, it will automatically compute the answer for the next equation. Another advantage is if information is inaccurate, you can go back and check your work with just a click, unlike using y calculations or by hand you have to erase so much and start all over again, which could be time......

...Using Microsoft Excel Getting Started Using Microsoft Excel About Excel What is a Spreadsheet? Microsoft Excel is a program that’s used for creating spreadsheets. So what is a spreadsheet? Before personal computers were common, “spreadsheet” referred to large sheets of lined paper, which were used by people in various businesses to record facts and figures in rows and columns, and then make calculations based on the information. When personal computers first began appearing, one of the first applications was a program released in 1979 called VisiCalc. It was used as a tool for performing spreadsheet style calculations that would have been to difficult to do on a calculator. The program quickly became so popular that people began buying personal computers for their businesses just so they could use VisiCalc. VisiCalc Since then, many other spreadsheet programs have been popular over the years, such as Quattro Pro and Lotus 123. Microsoft Excel was first released in 1985 with newer versions being released every couple of years. The most recent version is Excel 2003 (version 11). © Stephen O’Neil 2005 Page 1 Of 17 www.oneil.com.au/pc Using Microsoft Excel Getting Started How Do Spreadsheets Work?
