| scientific method | an organized set of steps to follow |
| hypothesis | prediction or possible answer to a scientific question |
| variable | a factor that changes in an experiment |
| dependent variable | the variable that is being observed or measured and lies on the y-axis in a graph |
| independent variable | the variable that is purposely changed and tested and lies on the x=axis during an experiment |
| constant | a factor in an experiment that does no change |
| control | a standard to which all results are compared |
| bias | an opinion favoring one side or another; a predisposition that affects how all results are perceived. |
| model | a physical representation of an idea, theory, of object |
| theory | an attempt to explain something |
| scientific law | describes a natural phenomenon , often mathematically based; much accumulated evidence, appears to be without exception |
| technology | applied science |
| experiment | to test one variable against another under controlled conditions |
| data | information collected during the experiment (numbers, measurements, observations) |
| inference | assumptions about observations based on past experiences and knowledge |
| observation | information or facts obtained by using the five senses |
| scientific theory | summarizes a set of hypothesis supported with repeated testing; has yet to be disproven |
| subjective data | opinionated, possibly bias; influenced by personal feelings or experiences |

| experimental investigation | an investigation used to find the cause of an event |
| observation | a way to gather information using your senses |
| prediction | a statement of what a scientist thinks will happen based on an observation |
| graph | picture/visual format for displaying data; major tool for communicating ABA results |
| vertical axis | represents target behavior/dependent variable; |
| horizontal axis | Passage of time, whole units/ independent variable |
| linear graph | a line graph in which the data points yield a straight line |
| nonlinear graph | a line graph in which the data points do not yield a straight line |
| significant figures | all the digits in a measurement that have been measured exactly plus one digit whose value has been estimated |
