Taking {sampling}| one value {sample, population} from a population can be random {random sample}. Sample sets {aggregate, population} have number of samples {sample size}.
attributes
Samples have properties {parameter, population} {sampling statistic}, such as weight. Samples have property values {attribute data} {measurement data}, such as high weight. Sampling can infer {statistical inference} population mean, variance, mode, and median.
types
Random samples can have same subgroup proportions as population {stratified random sample}, such as same age distribution.
Sampling can return sampled member to population {sampling with replacement} or not {sampling without replacement}.
subsets
Sample subsets {sample class} share an attribute, such as high weight.
