To learn Basic Excel - Data Entry, Formulas and Functions
- 1. EXCEL BASICS Mrs.V. JAYAVANI Assistant Professor Department of Computer Science E.M.G. Yadava Women’s College
- 2. EXCEL BASICS This is a row. Rows are represented by numbers along the side of the sheet. This is a column. Columns are represented by letters across the top of the sheet. Excel spreadsheets organize information (text and numbers) by rows and columns:
- 3. EXCEL BASICS A cell is the intersection between a column and a row. Each cell is named for the column letter and row number that intersect to make it.
- 4. DATA ENTRY There are two ways to enter information into a cell: 1. Type directly into the cell. Click on a cell, and type in the data (numbers or text) and press Enter. 2. Type into the formula bar. Click on a cell, and then click in the formula bar (the space next to the ). Now type the data into the bar and press Enter.
- 5. DATA ENTRY 1. Open Excel (Start All Programs MS Office Excel). 2. Enter the following information into your spreadsheet:
- 6. FORMULAS AND FUNCTIONS ◦ Formulas are equations that perform calculations in your spreadsheet. Formulas always begin with an equals sign (=). When you enter an equals sign into a cell, you are basically telling Excel to “calculate this.” ◦ Functions are Excel-defined formulas. They take data you select and enter, perform calculations on them, and return value(s).
- 7. MORE ON FUNCTIONS ◦ All functions have a common format – the equals sign followed by the function name followed by the input in parentheses. ◦ The input for a function can be either: ◦ A set of numbers (e.g., “=AVERAGE(2, 3, 4, 5)”) ◦ This tells Excel to calculate the average of these numbers. ◦ A reference to cell(s) (e.g., “=AVERAGE(B1:B18) or “=AVERAGE (B1, B2, B3, B4, B5, B6, B7, B8)” ◦ This tells Excel to calculate the average of the data that appear in all the cells from B1 to B8. ◦ You can either type these cell references in by hand or by clicking and dragging with your mouse to select the cells.
- 8. FUNCTIONS FOR DESCRIPTIVE STATISTICS =AVERAGE(first cell:last cell): calculates the mean =MEDIAN(first cell:last cell): calculates the median =MODE(first cell:last cell): calculates the mode =VARP(first cell:last cell): calculates the variance =STDEVP(first cell:last cell): calculates the standard deviation You may directly write the functions for these statistics into cells or the formula bar, OR You may use the function wizard ( in the toolbar) Below are several functions you will need to learn for this class. Try them out with the practice data set.
- 9. FUNCTIONS FOR DESCRIPTIVE STATISTICS Your Excel spreadsheet should now look like this:
