Practical Data Lab
Enter your readings and repeats from a physics practical. The lab averages the repeats, draws the error bars and finds the best and worst lines, so you can quote a gradient with its uncertainty.
What you can do
- Means of repeat readings, with uncertainty from half the range, a fixed value or a percentage
- Error bars in x and y
- The best-fit line, and the steepest and shallowest lines through every error bar
- Gradient and intercept with absolute and percentage uncertainties
- Values rounded to match their uncertainty, ready for a write-up
