VARIABLES
 Variable – Factors that can change in an experiment
 Manipulated Variable – The variable that you purposely
change and test.

Terms continued
 Qualitative – Descriptions that do not use numbers.
 Quantitative – Descriptions using numbers. Counting objects or
measure them with standard units.
 Inferring – Explaining or interpreting an observation or statement.
 Predicting – Making an inference about a future event based on
current evidence or past experience.
 Classifying – Organizing objects and events into groups according
to a system, or organizing idea.
 Models – Pictures, diagrams, or other representations of objects or
processes.
 Measuring – Comparing an object or process to a standard.
Ways To Display Data
 Data Table – is an organized arrangement of information
in labeled rows and columns.
 Bar Graphs – is a diagram in which data about separate
but related items are represented by
rectangular shapes called bars.
 Line Graphs – is used to display data that show how one
variable (the responding variable)
changes in response to another variable
(the manipulated variable).
 Circle Graph – shows data as parts of a whole.
