Scientific method

The Scientific method

• A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.

• a hypothesis, testing the hypothesis, and stating conclusions.

• the hypothesis, and stating conclusions.

• all of the above

Variables

• In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.

• An experiment in which only one variable is manipulated at a time.

• factors that can change in an experiment

• A variable that a scientist changes to find out how this change affects other variables in the experiment.

Controlled experiment

• A variable that a scientist changes to find out how this change affects other variables in the experiment.

• An experiment in which only one variable is manipulated at a time.

• Data that is represented by measurements or counting.

• Facts and statistics collected together for reference or analysis

experimental group

• A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.

• A testable prediction, often implied by a theory

• Observation, Form a hypothesis, Designing a controlled experiment, Record and Analyze results

• the group in an experiment that receives the variable being tested

Control group

• A hypothesis that has been tested with a significant amount of data

• the group in an experiment that receives the variable being tested

• In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.

• Facts and statistics collected together for reference or analysis

Constant

• The outcome factor; the variable that may change in response to manipulations of the independent variable.

• A variable that a scientist changes to find out how this change affects other variables in the experiment.

• Information obtained through the senses.

• A value that does not change

Independent variables

• A variable that a scientist changes to find out how this change affects other variables in the experiment.

• The outcome factor; the variable that may change in response to manipulations of the independent variable.

• A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.

• A value that does not change

Dependent variables

• A hypothesis that has been tested with a significant amount of data

• A variable that a scientist changes to find out how this change affects other variables in the experiment.

• The outcome factor; the variable that may change in response to manipulations of the independent variable.

• A summary based on evidence or facts

• Theory

• Qualitative data

Hypothesis

• Facts and statistics collected together for reference or analysis
