Experimental Design Review

Define the term 'observations' in the context of an experiment.

• Data collected during an experiment

• The hypothesis of the experiment

• The conclusion drawn from the experiment

• The variables controlled in the experiment

Define the term 'inference' in the context of an experiment.

• A conclusion drawn from evidence and reasoning

• A hypothesis that is tested during the experiment

• A variable that is manipulated in the experiment

• A method used to collect data in the experiment

Define the term 'hypothesis' in the context of an experiment.

• A hypothesis is a statement that can be tested by an experiment.

• A hypothesis is a summary of the results of an experiment.

• A hypothesis is a detailed description of the experimental procedure.

• A hypothesis is a list of materials needed for an experiment.

Define the term 'variable' in the context of an experiment.

• A factor that can be changed or controlled in an experiment

• A constant value used in all experiments

• A tool used to measure experimental outcomes

• A hypothesis that is tested in an experiment

Define the term 'constant (controlled variables)' in the context of an experiment.

• Variables that are changed to see their effect on the experiment

• Variables that are kept the same throughout the experiment

• Variables that are measured during the experiment

• Variables that are not considered in the experiment

In the context of an experiment, what is the term 'independent variable' defined as?

• A variable that is manipulated to observe its effect on the dependent variable

• A variable that is measured to see the effect of changes in the independent variable

• A constant variable that does not change during the experiment

• A variable that is used as a control in the experiment

Define the term 'dependent variable' in the context of an experiment.

• The variable that is manipulated by the researcher

• The variable that is measured and affected in the experiment

• The variable that remains constant throughout the experiment

• The variable that is used as a control in the experiment

What is one characteristic of a good experiment?

• It has a large number of variables.

• It is repeatable and produces consistent results.

• It is based on assumptions.

• It has a complex design.

A good experiment can be repeated by anyone and get the same results. True or False?

• True

• False

In a good experiment, how many variables should be tested at one time?

• One

• Two

• Three

• Four
