| data table | A set of data elements using a model of vertical columns and horizontal rows. |
| levels of independent variable | The experimental independent variable levels of comparison. |
| independent variable (manipulated) | The one factor that a scientist changes during an experiment; also called manipulated variable. |
| dependent variable (responding) | The factor that changes as a result of changes to the manipulated, or independent, variable in an experiment; also called responding variable. |
| repeated trials | The number of trials performed during a scientific experiment to receive more accurate results. |
| mathematical means | Analysis of results by calculation in a data table. |
| graph | A diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles. |

| scatterplot | A graph of plotted points that show the relationship between two sets of data. |
| line plot | A graph that shows the frequency of data along a number line, best when comparing fewer than 25 numbers. |
| histogram | A diagram consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to the class interval. |
| constant | Continuous over a period of time, does not change. |
| control | A group or individual used as a standard of comparison for checking the results of a survey or experiment. |
| conclusion | Summarize how your results support or contradict your original hypothesis. |
