Chapter 1 1 What is the meaning of each of the following error messages NAME N A REF Value Num Div 0 If you enter 1 149 25 what value would result Insufficient Cell width Unrecognized text in formula No Answer Invalid cell reference Wrong Argument type Invalid numeric values in a formula or function Division by zero 2 The cell would display 1 149 25 3 If you enter 2 4 10 exactly as shown what value would result 4 List the orders of operations in order 1 Parenthesis 2 Exponentiation 3 Multiplication Division 4 Adding and subtracting 42 11 5 When writing formulas why is it preferable to use cell reference rather than typing in values 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 incorrect The most likely reason is that the format chosen for A1 and A2 will not show decimals Therefore if cell A1 is 1 4 and cell A2 is 2 4 the result in cell A3 is actually 3 8 which is displayed as 4 when rounding 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 8 What formula would you write to do each of the following a Add a range of numbers in cells A2 X2 b Find the largest value in cells C2 C8 c Find the smallest value in cells B2 through Z12 d Find the average value in cells C1 through C10 ignoring blank cells e Find the total number of values in cells C1 10 excluding any that contain text SUM A2 X2 MAX C2 C8 MIN B2 Z12 AVERAGE C1 C10 0 COUNT C1 C10 9 Define the following terms syntax arguments and algorithm Syntax The specific format of a function including the function name and the order of the arguments Arguments A function input when putting a number and how many decimal places 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 the formula B 4 SUM C1 C5 is copied from cell A9 to cell C10 what is the resulting formula 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 4 SUM E2 E6 SUM A2 B 1 12 What new formula results for each of the following if the formula is copied from cell C10 to cell E13 A1 A2 A 1 A2 A1 A2 A 1 A2 C4 C5 A 1 C5 A4 C5 C 1 C5 are contiguous and in the same workbook SUM Sheet1 B1 Sheet2 B1 Sheet3 B1 13 What formula could you use to add up cell B1 from Sheet1 Sheet 2 and Sheet 3 assuming the worksheets 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 2 5 4 3 1 2 7 2 What is the median value of the set 2 5 4 3 1 2 7 3 What is the mode of the data set 2 5 4 3 1 2 7 AVERAGE 2 5 4 3 1 2 7 MEDIAN 2 5 4 3 1 2 7 MODE 2 5 4 3 1 2 7 4 The data set 2 5 4 3 1 2 7 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 Since Standard deviation is the measure of range and distribution the larger standard deviation would result in a larger 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 37 50 What algebraic expression could you use to determine the percent increase in labor costs Note that a resulting value is not required 37 50 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 345 43 0 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 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 COUNTIF A2 A10 GM 12 Using the worksheet shown in Question 11 write a formula to determine the number of cars that cost less than 20 000 COUNTIF B2 B10 20000 SUMIF A2 A10 Ford B2 B10 worksheet for question 11 13 Using the worksheet shown in Question 11 write a formula to determine the total value of all Ford cars 14 Explain the difference between a What if analysis and Goal Seek by giving an example based on the 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 most 16 If each car shown in Question 11 is marked up between 50 and 250 increments what function could be used to randomly assign the amount to be added to the car price in this formula expensive car LARGE B2 B10 3 B2 RANDBETWEEN 50 250 17 The formula RAND gives what result Gives a random number between 0 and 1 to the nearest 10 ROUND AVERAGE A10 A20 1 AVERAGEIF A2 A10 Ford B2 B10 RANDBETWEEN 10 20 18 What formula could you write to average the values in cells A10 through A20 excluding blank cells rounded 19 Write a formula to determine the average price of only Ford vehicles using the worksheet in question 11 20 Write a formula to generate a random integer value between 10 and 20 1 List â€¦
