• Any quality, amount, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable.
• A sample is a subset of units chosen to represent all the individuals in a population. Because just a portion of the population was counted, it is only a partial enumeration. To estimate the characteristics of the total population of interest, data from the sampled units is used.
• A statistic is a numerical representation of a sample, whereas a parameter is a numerical representation of the entire population.
