Observing
What do we call a random guess with little to no background info?
Prediction
What do we call the testable explanation to a problem or question?

Inference
What do scientists use to test a hypothesis?
An Experiment
Can a hypothesis be proven right or wrong?
It can only be supported or rejected
What are the variables that are controlled for in an experiment or kept the same?
Constants
What is the variable that is intentionally manipulated by the experimenter/ the variable that is changed?
The Independent Variable
Which variable responds to the variable that was changed on purpose, and can be measured?
The Dependent Variable
What is the name of the group in an experiment that receive treatment or the thing that is being tested?
The Experimental Group
What do we call the group that does not receive treatment and is only used as a standard of comparison?
The Control Group
What are the step-by-step written instructions that inform you how to conduct an experiment?
Procedures
What kind of data involves the gathering of numerical information?
Quantitative
What kind of data involves the gathering of physical descriptions obtained through observations?
Qualitative
When all of your data is numerical and covers a span of time, which type of graph would best represent the information?
A Line Graph
If data gathered involves percentages, which type of graph will best represent the information?
A Pie Graph/Chart
What type of line is used to show the trend or pattern in the points plotted on a scatter plot?
The Line of Best Fit
What are some things that all graphs must include?
Labels
X-axis
Y-axis
Title

If data collected during in the experiment provides evidence for the hypothesis, we say that it is…
Supported
When many scientists obtain the same results for an experiment, the hypothesis can become a…
