Introduction to Spreadsheets Presented by Frank H. Osborne, Ph. D. © 2005 ID 2950 Technology and the Young Child

Basic Considerations A spreadsheet is basically a sheet of paper with columns and rows like you would use to keep business records.

Basic Considerations The columns and rows form a grid. Each column has a letter at the top and each row has a number at the side.

Basic Considerations Where each column and row intersect is a cell. In this picture the cursor is in cell A1.

Basic Considerations A typical computer spreadsheet has 256 rows identified as A through IV and 65536 rows. This gives a total of 16,777,216 cells. A cell contains data. Data can be –constants (numbers) –labels (such as column headings) –formulas (for calculations)

Basic Considerations Spreadsheets are useful in a variety of disciplines. These include: –business - for financial records –science - for data analysis and calculations –math - for graphing, formulas and statistics Spreadsheets are used in all disciplines where data analysis, graphs and charts are needed.

Spreadsheet Data Types Constants –Constants are numbers. Numbers may be whole numbers or decimals. –Numbers can also be currency, fractions, scientific notation, and percentages

Spreadsheet Data Types Labels –Any type of text, such as column headings or identifiers in lists. –Text can have a variety of fonts and pitch sizes. –Cells can have borders and underlines. –Cells can have different colors than the background for emphasis purposes.

Spreadsheet Data Types Formulas –Formulas are used for calculations. All formulas must begin with the equals (=) sign. –When a formula is in a cell, the spreadsheet displays the value of the formula, not the formula itself. –You can see the formula in the formula bar.
