To allow scientists to make precise forecasts

To aid scientists in formulating theories

To steer scientists in their studies and experiments

To offer a systematic procedure for scientists to explore natural events, make observations, establish hypotheses, carry out experiments, scrutinize data, and reach conclusions.

A hypothesis is used to confirm personal beliefs without any testing.

A hypothesis is a random assumption that does not need any evidence.

A hypothesis is a tentative explanation or prediction that can be tested through scientific methods.

A hypothesis is a conclusion based on personal opinion, not on scientific research.

A variable that is measured or observed in an experiment.

A variable that is manipulated or controlled by the experimenter.

A variable that is randomly assigned to participants.

A variable that is not affected by other variables.

A dependent variable is the outcome or response variable that is affected by the independent variable.

A dependent variable is a variable that is manipulated by the researcher to observe its effect on the independent variable.

A dependent variable is a variable that is not influenced by any other variables.

A dependent variable is a variable that is affected by the independent variable.

They are the variables that are adjusted to see the effect on the outcome

They are the variables that are observed as a result of the experiment

They are the variables that are maintained the same to ensure the experiment is fair

They are the variables that are chosen randomly for the experiment

observation

questioning

experimentation

conclusion

The dependent variable

The independent variable

Both the independent and dependent variables

Neither the independent nor the dependent variables

The outcome of the experiment based on different conditions

The units used to measure the dependent variable

The temperature at which the experiment is conducted

The number of trials conducted in the experiment

To change the dependent variable

To observe the independent variable

To ensure all variables are manipulated except the dependent variable

To provide a standard of comparison for the experimental group

It is the variable that is manipulated

It is the variable that is measured

It is the variable that is kept constant

It is the variable that is not used
