Definitions Workbook: a workbook is an excel file that contains one or more worksheets Worksheet: single spreadsheet that contains cells organized by rows and columns Rows: horizontal lines of information, represented by numbers Columns: vertical lines of information, represented by letters Cell: intersection of a row and a column Cell Address: column letter + row number. e.g. B5, C16 Range: 2 or more adjacent cells that are selected at the same time. e.g. A1:A3, A2:D2, B1:D5 Argument Set: range of cells for function. e.g. =SUM (B1:B5) Label: name. Identifying phrases for numeric data.

Formula Formula: combination of numeric constants, cell references, arithmetic operators and functions that is used to calculate a result Must start with an equal, “=”, sign Two types: 1) Mathematical Formula 2) Function

1) Mathematical Formula: writing the formula using arithmetic operators and numbers or cell addresses e.g. =10*(2+3)/2 OR =A1+A2 2) Function: formula that also begins with the equal sign but then followed by a descriptive name that is predefined in the software. e.g. =Sum(B1:B5), =Average(C5:D5) >>Argument Set: range of cells for function. e.g. =SUM (B1:B5)

Basic Functions SUM: adds all the numbers in a range of cells AVERAGE: calculates the arithmetic mean of its arguments MAX: returns the largest number in a selected set of values MIN: returns the smallest number in a selected set of values COUNT: counts the number of cells in a range that contain only numbers COUNTA: counts the number of cells in a range that are filled by letter and number
