Description
Return midpoint and half-width of a supplied switch interval.
Behavioral-economics tasks compare supplied payoffs, reference points, budgets and observed choices. A gap, dominance flag or response fraction illustrates a declared convention without identifying a psychological bias, predicting real choices or selecting a suitable financial action.
Return midpoint and half-width of a supplied switch interval.
When to use this tool
Use Choice Switch Interval Midpoint when checking the stated experimental payoff, budget, reference or choice convention.
How to use the tool and how it works
- Enter lowerValue, upperValue. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read midpoint, halfWidth. Use the output convention below.
Return midpoint and half-width of a supplied switch interval. Require lowerValue <= upperValue; midpoint = lower+(upper-lower)/2, halfWidth = (upper-lower)/2.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| lowerValue | Lower Value | Required. Finite number. |
| upperValue | Upper Value | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| midpoint | Midpoint | Required. Finite number. |
| halfWidth | Half Width | Required. Finite number. |

}Limitations and assumptions
- These are interval geometry values, not a confidence interval, an elicited preference or a demonstrated switch point.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use a well-defined study design and complete data to estimate behavior; assess real financial rights, consequences and uncertainty independently.
