Survey Validity Under Bias Calculator
See how much non-response bias your survey can withstand before losing validity
How it works: Test how bias affects your majority by adjusting the “bias multiplier” (k):
- k=1: No bias (non-respondents mirror respondents)
- k=3: Moderate bias (3x more likely to oppose)
- k=∞: Worst-case (all non-respondents oppose)

Survey’s Bias Resilience Calculator
How much bias can your survey results withstand before losing majority?
Purpose: Recalculates results under varying bias (k=1 to k=∞) to test majority resilience.
k-value: How many times more likely non-respondents are to oppose vs. respondents.
Example: k=3 means non-respondents are 3× more likely to say “no.”
