Welcome! To the Science Fair Graphs & Numbers Tutorial For your science project, you created three electromagnets made of three different kinds of wire -- Small, Medium and Large gauge. You tested each magnet to see how many nails it would pick up. You want a BAR CHART to show your results. YOUR DATA IS... 1-2-3 steps to CREATE a BAR CHART: ---------------------- ----------------------------------- MAGNET NAILS 1. Create a NEW database ---------- --------- 2. Enter the data SMALL 31 3. Select the graph to display MEDIUM 38 LARGE 51 STEP 1: From the "FILE" pull-down menu, choose New Database. You are asked to enter the name for your new database. Enter a name, like "MAGNETS", of up to 8 characters. (No blanks in the name.) Choose the database type from a list of pre-defined databases, or you can create a custom database. To create a BAR CHART, choose the SIMPLE BAR CHART Option. STEP 2: ENTER DATA - This is where you enter your results of your experiment -- the data entry screen. Enter the data for the first magnet as record 1. Your first Label is SMALL (small wire) Your first Value is 31 (number of nails) Type SMALL (press Enter), type 31 (Press Enter), then enter the numbers for records 2 and 3. Press F7 (Exit) to end entry. STEP 3: CHOOSE WHAT GRAPH TO USE: For this example, choose the Descriptive Statistics and Graph from the ANALYZE pull-down menu, then choose the Bar Graph option. NOTE: Once the graph is displayed, you can use the menu at the top of the screen to change colors, patterns, titles, and so on for each graph. Science Fair Graphs & Numbers allows you to create these kinds of graphs and calculations: o Bar Chart, Pie Chart, Line Chart, Area Chart o Histogram, Box and Whiskers, Normal Curve o Cumulative Distribution, Stem and Leaf Plot o X-Y Scatterplot o Time Series Plot o Calculate statistics
