Sample size formulas are typically used for probability samples to ensure representative and reliable results. Nonprobability samples, on the other hand, do not have a known sampling frame or a way to control for selection bias, making it difficult to calculate an appropriate sample size. Therefore, sample size formulas cannot be used for nonprobability samples.
