Inferences and conclusions give you a powerful tool for understanding people and the decisions they make. An inference is an assumed fact, based on information you have at your disposal. A drawn conclusion is an assumption developed as a next logical step for the given information. You can employ inferences and conclusions together to increase the accuracy of your conclusions and learn to better understand the people around you.

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.

The control group is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.

Hypothesis: a scientific prediction that must be confirmed or not...

In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of the phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.

Data:acts and statistics collected together for reference or analysis.

Bias:prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.

Line graphs can also be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.
