Advanecd Error BArs

The following concepts/skills are covered in the following video.

  1. Adding constant error bars
  2. Adding percentage error bars
  3. Adding custom error bars

Interpreting R2 Values

The following concepts are covered in the following video.

  1. Supports a hypothesized model
    • Sufficient data + high R2 for the hypothesized model function
  2. Refutes a hypothesized model
    • Sufficient data + low R2 for hypothesized model function
  3. Inconclusive
    • Insufficient/noisy data + high R2 for hypothesized┬ámodel function
    • Insufficient/noisy data + low R2 for hypothesized┬ámodel function
    • Similar R2 for hypothesized model function and one or more other functions with the same number of free parameters.
