Objectives Semi-Selection Pointing Paste Special Select page setup options Print a workbook Functions 1/12/2019

Cell referencing Used in formulas so that they can be copied and reused easily. In some cases, we want the references to cells to move down, or over as we copy the formula. In other cases, we do not want the reference to change even if we do move. 1/12/2019

Relative vs. Absolute Addressing Relative cell references change relative to the direction in which the formula is copied Absolute cell references are exact; they do not change when a formula is copied Indicated by dollar ($) signs in front of the column letter and row number Most often used when the value need not change Use the F4 key to toggle between relative and absolute cell referencing 1/12/2019

Cell References(Contd) Relative reference A1 Column absolute mixed reference $A1 Row absolute mixed reference A$1 Absolute reference $A$1 1/12/2019

Avoiding Circular References A circular reference error occurs if a formula refers to itself 1/12/2019

Semi-selection(Pointing) Semi-selection uses the mouse pointer to build a formula containing cell references or ranges Click the cell where you want to create the formula. Type ‘=‘ sign . Drag the cell range that contains the value. Type the operators. Continue selecting the cell ranges . Press enter to complete the formula. 1/12/2019

Paste Special The Paste Special command is used to paste data from the clipboard using a different format 1/12/2019

Functions Function is a pre-constructed formula that makes difficult computations less complicated. Excel provides many inbuilt functions- Already has the formula information; just requires cell references. Take values, perform operations, and return results. When using functions adhere to the syntax A function begins with the equal sign (=) followed by the function name and arguments in parentheses Example: =SUM(A1:A3) 1/12/2019

Inserting a Function When a function is typed, Formula AutoComplete displays a list of functions matching the partial entry Use the Insert Function dialog box to search for a function or select one from a list. 1/12/2019

SUM SUM is the most commonly used function represented by a sigma () Adds values within a specified range Syntax refers to the grammatical structure of a formula Must adhere to stated structure of formula Arguments are values ─ used as input and returned as output Example: = Sum (B1:B10) Function Name Arguments 1/12/2019

AutoSum Automates the SUM function Click the cell where you want the result Click AutoSum button Select the range of cells you want to sum Press Enter to complete Excel Chapter 3 1/12/2019

Basic Statistical Functions Perform a variety of calculations to aid in decision making process AVERAGE calculates the average of a range of numbers MEDIAN finds the midpoint value in a range MIN calculates the minimum value in a range MAX calculates the maximum value in a range COUNT counts the number of values within a range Excel Chapter 3 1/12/2019

COUNT Statistical Functions – COUNT, COUNTA COUNT function counts the number of cells in a range that contain numerical data. COUNTA function counts the number of cells in a range that are not blank. COUNTBLANK counts the number of blanks in the given range. Ex: COUNT(C6:C24) COUNTA(E2:E10) COUNTBLANK(J9:J16) Excel Chapter 3 1/12/2019

Date Functions Efficiently handle time-consuming procedures Excel treats date as serial numbers so we can perform calculations using dates.

IF Function Used to determine whether a given condition has been satisfied or not When the condition is met, the formula performs one task; when it is not met, the formula performs another task Has three arguments: a condition tested to determine if it is true or false the resulting value if the condition is true the resulting value if the condition is false Excel Chapter 3 1/12/2019

Lookup Functions Lookup functions are used to look up values in a table to perform calculations or display results A Lookup table is a range that contains data for the basis of the lookup and data to be retrieved. Excel Chapter 3 1/12/2019

VLOOKUP Used to gauge an entered value against a range of corresponding results Well suited for large tables of data, such as tax tables Also to convert the number grades into letter grades Has three mandatory arguments Excel Chapter 3 1/12/2019

VLOOKUP(contd.) Syntax =VLOOKUP(lookup value , lookup table , column index number , [range lookup]) The lookup value ─ value to look up in a reference table The lookup table ─ a range of cells containing the reference table The column index number ─ the column number in the lookup table that contains return values Excel Chapter 3 1/12/2019

Example Converting the Number grades to the letter grades Excel Chapter 3 1/12/2019

The loan is paid off in 2 years (ie: 2 x 12). E2 - 7% ; E3 - 24 ; E4 - $5,000.00 PMT ( E2/12 , E3 , - E4 ) Excel Chapter 3 1/12/2019

FV Function Used to determine the future value of an amount, such as an investment Has three arguments: The interest rate (also called the rate of return) The number of periods (how long you will pay into the investment) The periodic investment (how much you will invest per year) Syntax: FV(rate, nper, pmt,[pv],[type]) Excel Chapter 3 1/12/2019
