Chapter 1 1 What is the meaning of each of the following error messages a Column width of the cell is too narrow or the formula in the cell results in a negative date b NAME Unrecognized test in a formula c N A No answer can be found d REF Invalid cell reference e Value Wrong argument type or operand f NUM Invalid numeric values in a formula g DIV 0 Division by zero 2 The formula 1 100 25 is entered into a cell exactly as shown Will Excel be able to calculate a result based on this formula Explain No Excel will not be able to calculate this because it has a comma Excel will ask you if you meant to type 1100 25 This is the proper formula which will work and result in a 44 3 If you enter 12 1 10 in a cell exactly as shown what would result 4 List each of the following operations in order of precedence from first to last 2 Parenthesis Exponentiation Multiplication Division Adding and subtracting 5 When you write a formula why should you cell reference rather than typing in values directly into the formula Using cell references is preferable to directly inputting values into a formula because it allows the user to easily update the spreadsheet without having to know exactly 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 to be incorrect The most likely reason is that the format chosen for A1 and A2 will not show decimals Therefore if cell A1 is 1 6 and cell A2 is 1 5 the result in cell A3 is actually 3 1 which is displayed as 3 when rounding 7 Referring to the preceding worksheet if you wrote the formula B1 5 what value would result assuming the displayed value is the precise value 5 8 What formula would you write to do each of the following a Add a range of numbers in cells B2 B12 SUM B2 B12 b Find the largest value in cells C2 F2 MAX C2 F2 c Find the smallest value in cells A1 though X10 MIN A1 X10 d Find the average value in cells C1 through C10 assuming blank cells will be ignored AVERAGE C1 C10 0 e Find the total number of values listed in cells A1 through F1 excluding any that contain text COUNT A1 F1 9 Define the following terms a Syntax The specific format of a function including the function name and the order of the arguments b Arguments A function input when putting a number and how many decimal places c Algorithm A rule that governs how a function works A systematic set of procedures that the computer always steps through to calculate the results of a function 10 If you copy the formula B 4 SUM C1 C5 from A9 to B11 what is the resulting formula B 4 SUM D3 D7 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 B 1 A2 12 What new formula results for each of the following formulas if you copy it from cell C10 to cell E12 A1 A2 C3 C4 A 1 A2 A 1 C5 A1 A2 A4 C5 A 1 A2 C 1 C5 13 What formula could you use to add up cell C1 from Sheet1 Sheet 2 and Sheet 3 assuming the worksheets are contiguous and in the same workbook SUM Sheet1 C1 Sheet2 C1 Sheet3 C1 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 discount A1 discount A2 Chapter 2 1 What formula could you write to calculate the mean of the following data set 4 10 8 6 2 4 14 AVERAGE 4 10 8 6 2 4 14 2 What is the median value of the set 4 10 8 6 2 4 14 MEDIAN 4 10 8 6 2 4 14 3 What is the mode of the data set 4 10 8 6 2 4 14 MODE 4 10 8 6 2 4 14 4 The data set 4 10 8 6 2 4 14 has a standard deviation of 4 14 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 Since Standard deviation is the measure of range and distribution the smaller standard deviation would result in a smaller range of values 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 40 What algebraic expression could you use to determine the percent increase in labor costs Note that a resulting value is not required 40 35 35 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 710 52 1 results in what precise value 8 Write a formula to round up 63 34 to the nearest percent ROUNDUP 63 34 2 9 What is the symbol for the less than or equal to relational operator in Excel 10 What is the symbol for the not equal to relational operator in Excel 11 Review the following worksheet and then use the COUNTIF function to write a formula that determines the number of Ford cars on this list False 710 12 Using the worksheet shown in Question 11 write a formula to determine the number of cars that cost more than 20 000 13 Using the worksheet shown in Question 11 write a formula to determine the total value of all GM cars COUNTIF A2 A10 Ford COUNTIF B2 B10 20000 SUMIF A2 A10 GM B2 B10 14 Explain the difference between a What if analysis and Goal Seek by giving an example based on the worksheet for question 11 What if to determine the outcome of changing one or more input values and evaluate the recalculated results For example you could determine how changing the price of a Ford would affect the total cell Goal Seek tool that allows you to work backward to determine the input required that will ensure a specific outcome For example you could use goal seek to determine what price a Ford needs to be to make the total value over 200 000 15 Using the worksheet shown in Question 11 write a formula to determine the value of the third least expensive car SMALL B2 B10 3 16 If each car shown in Question 11 is marked up between 100 and 200 increments what function could be used to randomly assign the amount to be added to the car price in this formula B2 RANDBETWEEN 100 200 17 The formula RAND …
