All of these factors affect the size of a sample needed when working with a probabilistic sample. The amount of diversity or variation of the parameter affects the sample size as more variation requires a larger sample size for accurate estimates. How precise the estimate must be also affects the sample size as more precise estimates require larger sample sizes. The degree of confidence affects the sample size as higher confidence levels require larger sample sizes.
