| Histogram | a statistical graph of a frequency distribution in which vertical rectangles of different heights are proportionate to corresponding frequencies |
| Inferential statistics | Tools that are used to infer the results based on a sample to a population. |
| Inferential statistics | used to draw conclusions based on the numbers actually collected during a research study, but going beyond these numbers. |
| Interval | a set of real numbers between two numbers either including or excluding one or both of them. |
| Kurtosis | a measure of the extent to which a frequency distribution is concentrated about its mean. a measure of whether the data are peaked or flat relative to a normal distribution. |
| Levels of measurement | The level of measurement refers to the relationship among the values that are assigned to the attributes for a variable. There are typically four levels of measurement that are defined: Nominal; Ordinal; Interval; and Ratio. |
| Multimodal distribution | a statistical distribution of values with multiple peaks. |
| Nominal variables | the numerical values just "name" the attribute uniquely. |
| Normal curve | A graph representing the density function of the Normal probability distribution. AKA –Bell Curve. |
| Numeric variable | a variable that has the purpose of storing a numeric value. |
