Front

What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured for change in an experiment, often affected by the independent variable.

Front

When should a line graph be used instead of a bar graph?

Back

A line graph should be used if the data shows change over a continuous range (like temperature), while a bar graph is used for comparing categories.

Front

Which type of graph is best for showing changes over time?

Back

A line graph is best for showing changes over time.

Front

In an experiment testing the effect of sunlight on plant growth, what is the dependent variable?

Back

The dependent variable is plant growth.

Front

What is a control in an experiment?

Back

The control is the standard or baseline condition against which other conditions are compared, often an untreated or 'normal' condition.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is the purpose of a hypothesis in scientific experiments?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

Front

What is the significance of replicating experiments?

Back

Replicating experiments increases reliability and helps confirm that results are consistent and not due to chance.

Front

What is a variable in scientific research?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.
