Copy and paste the data in the table above into the x and y columns in the exponential regression applet below. You will have to copy and paste one column at a time. Another type of exponential scatterplot is exponential decay. This will be much easier to differentiate from quadratic.
| time | intensity |

1.00 0.61 0.37 0.22 0.13 0.08 0.04 0.02 0.01 0.01 |
Copy and paste the data in the table above into the x and y columns in the exponential regression applet below. You will have to copy and paste one column at a time.
After the data is in the applet, press plot and analyze data.
