Made for real tasks

Measure agreement of two continuous measurements using means, spreads, and Pearson correlation.

Load the example in the workspace to reproduce these results. Display rounding does not change the underlying calculation.

Enter first mean, second mean, first standard deviation, second standard deviation, pearson correlation.
Use the displayed units and confirm the model assumptions.
Calculate and compare the outputs against your input scenario.

Use means and variances computed with a consistent convention from the same paired observations; not a reliability confidence interval.
