Ans-COUNT() Counts the number of cells in a range of cells that are not blank Ans-COUNTA() Calculates the simple average of a set of numbers Ans-AVERAGE() Returns the largest value in a set of numbers Ans-MAX() Returns the smallest value in a set of numbers Ans-MIN() Calculates the interest rate earned for an investment Ans-RATE() Calculates the annual percentage rate for an interest rate Ans-EFFECT() Calculates the number of payments that will be made to pay off a loan Ans-NPER() Calculates the payment amount for a loan Ans-PMT() Calculates the current value of an investment (accounting for compound interest) Ans-PV() Calculates the future value of an investment Ans-FV() Combines Boolean expressions to determine if ALL of the combined expressions are TRUE Ans-AND() Combines Boolean expressions to determine if ANY of the combined expressions are TRUE Ans-OR() Check to see if a Boolean expression is not evaluated as TRUE Ans-NOT() Build on Boolean logic and specify the results depending on the results of the Boolean expression AnsIF() Determine (count) the number of cells within a range of cells that contain a specific value Ans-COUNTIF() Calculate the total (sum) for a set of values that match a specific criterion Ans-SUMIF() Calculate the average for a set of values that match a specific criterion Ans-AVERAGEIF() Returns the related value from the specified column after finding the match in the first column AnsVLOOKUP() Returns the related value from the specified row after finding the match in the first row Ans-HLOOKUP() The length, in number of characters, of a block of text Ans-LEN() The position of a specific character, word, or phrase within a block of text Ans-SEARCH() Returns the specified number of characters starting from the beginning of a block of text Ans-LEFT() Returns the specified number of characters from the middle of a block of text Ans-MID() Returns the specified number of characters starting from the end of a block of text Ans-RIGHT() Combines blocks of text Ans-CONCATENATE() Calculates the standard deviation for a sample. (Use STDEV.P to calculate the standard deviation for a population.) Ans-STDEV.S() The confidence interval or range of values that we believe the "true" population value falls into AnsCONFIDENCE.NORM() Calculates the correlation coefficient between two sets of values Ans-CORREL() Calculates, or predicts, a future value along a linear trend by using existing values Ans-FORECAST() ^^ How to calculate payment amount for a loan Ans-In the cell next to the word payment enter: =PMT(rate [select the field with the interest rate]/12 [you put /12 because its monthly and there are 12 months in a year], nper [select the field with the term], pv [select the field with the principal value] - this will produce the results Example: =PMT(C13/12, C12, C11) ^^ Calculate, in cell D20, the interest amount for period 1 by multiplying the balance in period 0 (cell F19) by the loan interest rate (cell C13) divided by 12. Dividing the interest rate by 12 results in the monthly interest rate. This formula is reusable. The interest for a given period is always the monthly interest rate times the balance from the previous period. [3 points] Ans-In the proper cell do the following: ={select the field mark balance}*{select field marked interest rate - be sure to add a $ in the field because you do not want the interest rate to change at all}/12 EXAMPLE: =F19*C$13/12 ^^ Copy the principal amount calculation down to complete the "principal" column of the amortization table. [2 points] Ans-Simply click the corner of the field you want to copy, then highlight all the fields you want it to copy to and let go. It will copy down ^^ Calculate, in cell F20, the balance for period 1. The balance is the difference between the balance for period 0 (cell F19) and the principal amount for period 1 (cell E20). This formula is reusable. The balance is always calculated as the difference between the balance from the previous period and the principal amount for the current period. Ans-Follow the instructions carefully Example =F19-E20 ^^ Calculate the total interest paid in cell G13. The total interest paid is the sum of all interest paid in the "Interest" column of the amortization table. Ans-=sum(highlight from start to finish all the fields you are adding together) Example: =SUM(D20:D67) ^^ Check to see if the total interest calculation in the amortization table is correct. The total interest paid is equal to difference between total amount paid over the course of the loan and original loan amount. Insert a formula into cell G14 to calculate the difference between the total amount paid and the original loan amount. Notice the negative sign associated with the original loan amount. This value should equal the total interest calculated using the amortization table Ans-={select field of total overall amount paid} + {select original loan amount, you are doing + to offset the fact that the loan amount in this case is a negative number). This balance should equal total interest paid Example: =G12+C11 ^^ Use the HLOOKUP function to complete the "Hourly Wage" column of table 1. Use the "Employee" column of table 1 as the lookup_value and the "Employee Wage Information" above table 1 as your reference table. Ans-in the first open hourly wage column enter: =HLOOKUP([select the filed with the first employee name in it], [highlight the full employee wage table -adding $ after the letters of the fields so that the selected employee wage doe snot change], [enter which row you want to pull the hourly wage from, in this case it was row 2], [enter the word FALSE because you want an EXACT match] Example: =HLOOKUP(D16,D$11:H$12,2,FALSE) ^^ Use the AND function to complete the "Time Bonus?" column of table 1. An employee earns a time bonus if the project's "Hours Worked" are fewer than the "Estimated Hours" and if the work "Quality" is greater than 1 Ans-=and([select the field for hours worked][select field for estimated hours],[select field for quality]1) Example=AND(E16C16,H161) ^^ Use the OR function to complete the "Outcome Bonus?" column of table 1. An employee earns an outcome bonus if the difficulty of a job is greater than 3 or if the quality of their work is equal to 3. Ans- =or([enter the filed for difficulty]3,[enter field quality]=3) Example: =OR(G163,H16=3) ^^ Use the IF function to complete the "Time Bonus $" column of table 1. If an employee earns a time bonus (i.e., the corresponding cell in the "Time Bonus?" column is TRUE), then "Time Bonus $" is the "Job Pay" for that project times the bonus percentage in cell M11. Otherwise "Time Bonus $" is 0. Ans- =if([select field for time bonus]=true, [select field with job pay]*[select filed with time bonus -be sure to enter a $ between the letter and number for time bonus because you do not want the bonus % to change], 0 Example: =IF(I16=TRUE, K16*M$11, 0) ^^ Use the IF function to complete the "Outcome Bonus $" column of table 1. If an employee earns an outcome bonus (i.e., the corresponding cell in the "Outcome Bonus?" column is TRUE), then "Outcome Bonus $" is the "Job Pay" for that project times the outcome bonus percentage in cell M12; otherwise, "Outcome Bonus $" is 0. Ans-=if([select field for outcome bonus]=true, [select field with job pay]*[select filed with outcome bonus - be sure to enter a $ between the letter and number for time bonus because you do not want the bonus % to change], 0 Example =IF(J16=TRUE,K16*M$12,0) ^^ Use the IF function to complete the "Comments" column of table 1. Display "Good Job" if both the "Hours Worked" are less than or equal to the "Estimated Hours" for a project and the assessed "Quality" of that project is greater than 1. Display "Too Much Time" if the "Hours Worked" on a project exceed the "Estimated Hours" for that project; otherwise, display "Poor Quality." Ans-=if(and [use and here because it says if both][enter field for hours worked]=[enter field for estimated hours],[enter field for quality]1),"Good Job",IF(enter field hours worked][enter field estimated hours],"Too Much Time","Poor Quality")) Example =IF(AND(E16=C16,H161),"Good Job",IF(E16C16,"Too Much Time","Poor Quality")) ^^ Use the VLOOKUP function to complete the "Employee" column of table 2. Use "Job ID" from table 2 as your lookup_value(s) and table 1 as the reference table. Ans-=vlookup([enter job id field], [enter range that covers the job id through the employee name], [tell the computer which column from the range would you pull the name from - in this case it is the 3rd column] Example: =VLOOKUP(B40,B$16:D$35,3) ^^ Use the VLOOKUP function to complete the "Difficulty" column of table 2. Again, use "Job ID" from table 2 as the lookup_value(s) and table 1 as the reference table. Ans-=vlookup([enter job id field], [enter range that covers the job id through the difficulty ^remember the $ so the range doesn't change], [tell the computer which column from the range would you pull the name from - in this case it is the 6th column] Example: =VLOOKUP(B40,B$16:G$35,6) ^^ Use the COUNTIF function to complete the "# of Jobs" column in table 3. Reference the appropriate field in table 1 as your range and the "Employee" names in table 3 as your criteria. Ans-=countif([enter range of table to include employee name - do not forget the $ between the letter and number so that the range does not change], enter field showing employee name) Example: =COUNTIF(B$16:D$35,G39) ^^ Use the SUMIF function to complete the "Total Hours" column in table 3. Reference the appropriate field in table 1 as your range and the "Employee" names in table 3 as your criteria. Ans-=sumif([select range of employee name], select the field that holds the employee name in table 3,[select range of total hours]) Do not forget the $ to make sure the ranges do not adjust Example: =SUMIF(D$16:D$35,G39,E$16:E$35) ^^ Use the SUMIF function to complete the "Total Pay" column in table 3. Reference the "Employee" field in table 1 as your range, the "Employee" names in table 3 as your criteria, and the "Total Pay" field in table 1 as your sum_range. Ans-=sumif([select range of employee name], select the field that holds the employee name in table 3,[select range of total pay]) Do not forget the $ to make sure the ranges do not adjust Example: =SUMIF(D$16:D$35,G39,N$16:N$35)
