reference VALUE wrong argument type NUM invalid numeric values in the formula DIV 0 Divided by zero 2 If you enter 1 149 25 in a cell exactly as shown without an equal sign what value would result 3 If you enter 2 4 10 in a cell exactly as shown what value would result 1 149 25 42 4 List each of the following operations in order of precedence from 1 to 4 first to last Multiplication and division parentheses addition and subtraction exponentiation 1 Parentheses 2 Exponentiation 3 Multiplication and Division 4 Addition and Subtraction 5 When writing formulas why is it preferable to use cell references rather than typing in values It allows the user to easily update the spreadsheet without having to know which formula or formulas contain the changed value 6 In the worksheet below cell A3 contains the formula A1 A2 explain the most likely reason the value calculated appears incorrect The answer is rounded up because of the excel rounding feature 7 Referring to the preceding worksheet if you wrote the formula b1 110 what value would result assuming the displayed value is the precise value 11 8 What formula would you write to do each of the following a Add a range of numbers in cells A2 X2 Sum A2 X2 b Find the largest value in cells C2 C8 Max C2 C8 c Find the smallest value in cells B2 through Z12 Min C2 C8 d Find the average value in cells C1 through C10 assuming blank cells will be ignored Average C1 C10 e Find the total number of values listed in cells C1 through C10 excluding any that contain text Count C1 C10 9 Define the following terms Syntax specific name and order of a function Arguments The functions inputs Algorithm the way in which the function behaves 10 If the formula B 4 Sum C1 C5 is copied from cell A9 to cell C10 what is the resulting 11 Refer to the following worksheet What formula would you write in cell B2 that can be copied down the column and across the row to complete the multiplication table 12 What new formula results from each of the following if the formula is copied from cell formula b 4 Sum E2 E6 A2 B 1 C10 to cell E13 a A1 A2 C4 C5 b A 1 A2 A 1 C5 c A1 A2 A4 C5 d A 1 A2 C 1 C5 13 What formula could you use to add up cell B1 from Sheet1 Sheet2 and Sheet3 assuming the worksheets are contiguous and in the same workbook Sum B1 Sheet2 B Sheet3 B1 14 Cell B1 has been given the range name discount How would you write a formula in cell C1 that multiplies discount by cell A1 What new formula results if you copy this formula into cell C2 Product A1 Discount Product A2 Discount Chapter 2 Pages 153 154 1 What formula could you write to calculate the mean of the following data set 2 5 4 3 1 2 7 note that resulting value is not required AVERAGE 2 5 4 3 1 2 7 2 What is the median value of the data set given in question 1 3 What is the mode of the data set given in question 1 Median 2 5 4 3 1 2 7 MODE 2 5 4 3 1 2 7 4 The data set given in question 1 has a standard deviation of 1 58 as compared with another data set that has the same mean but a standard deviation of 2 5 What general differences would you expect to find between the two sets of data The larger standard deviation means that the data values are dispersed wider from the mean of that group 5 In the chapter the original labor rate for inspectors was given as 35 per hour However due to a contract renegotiation this value is now 37 50 What Algebraic expression could you use to determine the percent increase in labor costs note that a resulting value is not required Current Historical Historical 6 When using the Increase Decimal button on the toolbar the precise value in the cell is modified True or False 7 The formula ROUND 345 43 0 results in what precise value 8 Write a formula to round up 64 34 to the nearest percent ROUND 63 34 0 9 What is the symbol for greater than or equal to relational operator in Excel 10 What is the symbol for the not equal to relational operator in Excel False 345 11 Review the following worksheet and then use the COUNTIF function to write a formula that determines the number of GM cars on this list 12 Using he worksheet shown in question 11 write a formula to determine the number of 13 Using the worksheet shown in question 11 write a formula to determine the total value COUNTIF A2 A10 GM cars that cost less that 20 000 COUNTIF B2 B10 20000 of all ford cars SUMIF A2 A10 Ford B2 B10 third most expensive car LARGE B2 B10 3 14 Explain the difference between a what if analysis and Goal Seek by giving an example based on the worksheet shown in question 11 15 Using the worksheet shown in question 11 write a formula to determine the value of the 16 If each car shown in question 11 is marked up between 50 and 250 in dollar increments what function could be used to randomly assign the amount to be added to the car price in this formula B2 RANDBETWEEN 50 250 17 The formula RAND gives what result A random value between 0 and 1 blank cells rounded to the nearest 10 ROUND AVERAGE A2 10 A 20 1 in Question 11 AVERAGEIF A2 A10 Ford B2 B10 18 What formula could you write to average the values in cells A10 through A20 excluding 19 Write a formula to determine the average price of only Ford vehicles using the worksheet 20 Write a formula to generate a random integer value between 10 and 20 RANDBETWEEN 10 20 Chapter 3 Page 214 1 List and describe the significance of each of Tufte s five data graphics principles 1 Above all else show the data Reminder not to clutter a chart by adding unnecessary illustration or decoration 2 Maximize the data ink ratio within reason refers to the portion of the ink that is devoted to displaying the data versus the portion of graphic that can be removed without losing the data want less ink to display more data 3 Erase non data ink within reason part of the chart that decorates more than informs 4 Erase redundant data ink within reason ink that repeats information 5 Revise and edit Charts can be improved in the same way that writing is improved by revision and editing 2 How …
