| Observation | The process of obtaining information by using the senses. |
| Hypothesis | A tentative explanation for a phenomenon based on observation and prior knowledge. |
| Prediction | A statement made in advance that expresses the results that will be obtained from testing a hypothesis if the hypothesis is supported; the expected outcome if a hypothesis is accurate. |
| Experiment | A procedure that is carried out under controlled conditions to discover, demonstrate or test an idea. |
| Variable | A difference between individuals or samples in an experiment. Variables may be manipulated, responding or extraneous. |
| Experimental Group | In an experiment, a group that is identical to the control group except for one factor (manipulated variable) that is compared to the control group. |

| Data | Any pieces of information acquired through observation or experimentation. |
| Correlation | The linear dependence between two variables. |
| Statistics | The collection and classification of data that are in the form of numbers. |
| Mean | The number obtained by adding the data for given characteristics and dividing this sum by the number of individuals. |
| Distribution | The relative arrangement of the members of a statistical population usually shown in a graph. |
| Probability | The mathematically calculated likelihood of an event. |
| Sample | A group of individuals or events that are selected to represent a greater population. |
| Risk | The probability of an unwanted outcome. |
| Model | A pattern, plan, representation, or description designed to show the structure of workings of an object, system, or concept. |
