Math, statistics and calculus are all words that many students dread. However, math isn't so daunting if you understand how to use technology. Graphing calculators can perform a variety of functions, including the production of graphs. By learning how to use the functions of a graphing calculator, you are sure to simplify your math courses.
Instructions
1. Compile a list of data. Once you have the data, you are ready to proceed with the calculator. Data can come from experiments, an assignment or simply a textbook.
2. Enter your data into the lists by clicking the black button which says "Stat", select "1: Edit..."and then click "Enter". This will take you to your list section.
3. Enter data in L1 and L2. L1 will be your X-axis on the graph and L2 will be your Y-axis.
4. Click blue button that says "2nd", followed by smaller button above it, which says "Y=". You will find that above the "Y=", it reads "Stat plot".
5. Select Plot 1 and click "Enter". Turn the plot, or graph, on by highlighting "On".
6. Scroll down to "Type" to pick the specific type of graph you would like to use. The options are histogram, scatter-plot, line graph, bar graph, or box and whiskers.
7. Scroll down and verify that your X list is set to L1 and Y list is set to L2. This means that your X-axis will be the numbers you entered in L1 and your Y-axis will be the numbers you entered into L2.
8. Click the small gray button in the upper right corner that says "Graph". Your graph will appear.
Tips & Warnings
- For more advanced graphs, refer to your graphing calculator guide. According to Morton Bay College, check window values to ensure your graph will show up. Click "Window" and verify the X-min, X-max, Y-min and Y-max.
