Inferential Statistics ✔✔The analysis of data to reach conclusions, generalizations, and estimations based on a small sample of the population.

Statistics ✔✔The gathering, organizing, and interpreting of numerical data.

Moderating Variable ✔✔Variable that changes the effect of independent variable on the dependent variable.

Mediating Variable ✔✔Variable that explains the relationship between the independent and dependent variables.

Dependent Variable ✔✔Variable that is being measured or affected.

Independent Variable ✔✔Variable that is free to change in a given model.

Feasible Region ✔✔Area of the graph that satisfies all constraints.

Coefficient ✔✔Multiplier of the variable, as in linear equations or inequalities.

Constraint ✔✔Restriction that limits the degree in which a company can pursue its objective.
