Spreadsheets C268: Final OA Study Guide

Spreadsheets C268: Final OA Study Guide Adds the individual numbers or the numbers included in the range(s). SUM() Counts the number of cells in a range of cells that contain numbers. COUNT() Counts the number of cells in a range of cells that are not blank COUNTA() Calculates the simple average of a set of numbers AVERAGE() Returns the largest value in a set of numbers MAX() Returns the smallest value in a set of numbers MIN() Calculates the interest rate earned for an investment RATE() Calculates the annual percentage rate for an interest rate EFFECT() Calculates the number of payments that will be made to pay off a loan NPER() Calculates the payment amount for a loan PMT() Calculates the current value of an investment (accounting for compound interest) PV() Calculates the future value of an investment FV() Combines Boolean expressions to determine if ALL of the combined expressions are TRUE AND() Combines Boolean expressions to determine if ANY of the combined expressions are TRUE OR() Check to see if a Boolean expression is not evaluated as TRUE NOT() Build on Boolean logic and specify the results depending on the results of the Boolean expression IF() Determine (count) the number of cells within a range of cells that contain a specific value COUNTIF() Calculate the total (sum) for a set of values that match a specific criterion SUMIF() Calculate the average for a set of values that match a specific criterion AVERAGEIF() Returns the related value from the specified column after finding the match in the first column VLOOKUP() Returns the related value from the specified row after finding the match in the first row HLOOKUP() The length, in number of characters, of a block of text LEN() The position of a specific character, word, or phrase within a block of text SEARCH() Returns the specified number of characters starting from the beginning of a block of text LEFT() Returns the specified number of characters from the middle of a block of text MID() Returns the specified number of characters starting from the end of a block of text RIGHT() Combines blocks of text CONCATENATE() Calculates the standard deviation for a sample. (Use STDEV.P to calculate the standard deviation for a population.) STDEV.S() The confidence interval or range of values that we believe the "true" population value falls into CONFIDENCE.NORM() Calculates the correlation coefficient between two sets of values CORREL() Calculates, or predicts, a future value along a linear trend by using existing values FORECAST() ^^ How to calculate payment amount for a loan 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] 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] 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 p
