Probability- The relationships between samples and population. It's a mathematical framework for making inferences about populations based on sample data, assessing risks, and making informed decisions under uncertainty.
Random Sampling- A statistical technique where each member of a population has an equal chance of being selected for a sample.
-
Independent random sampling- The probability of selecting any particular individual is not influenced by the individuals already selected for the sample.
Random samples- a subset of individuals chosen from a larger population, where each member has an equal chance of being selected.
Sampling with replacement- a statistical method where each member of a population, once selected, is returned to the population pool before the next selection.
Random sampling with replacement- Random sampling that requires equal chance of selection and constant probabilities.
Random sampling without replacement- - A method where each member of a population can be selected only once for a sample. Once chosen, an individual is not returned to the population pool, ensuring no duplicates in the sample.
Frequency Distribution- A statistical tool that organizes data to show how often each value or range of values occurs within a dataset.
*Frequency distribution graph- represents how often each value or range of values occurs in a dataset.

Frequency polygon-A line graph connecting points that represent the frequency of data at the midpoint of each interval.
Pie chart- A circular chart divided into sectors, each representing a category's relative frequency as a proportion of the whole.
Normal Unit Table- This table lists proportions of the normal distribution for a full range of possible z-score values.

Column D- identifies the proportion of the distribution that is located between the mean and the z-score.
