- lower bound
- Any number less than or equal to all elements in a set.
- margin of error
- a statistic expressing the amount of random sampling error in the results of a survey.

σ_{p}+ z-score - point estimate
- the process of finding an approximate value of some parameter—such as the mean (average)—of a population from random samples of the population.
- point estimate and margin of error
- sample size
- measures the number of individual samples measured or observations used in a survey or experiment.
