CJH Variables and Graphs 6th Grade

Front

What is a dependent variable?

Back

The dependent variable is the factor that is measured or observed in an experiment. It changes in response to the independent variable.

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is a control variable?

Back

Control variables are factors that are kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

What is the purpose of conducting more trials in an experiment?

Back

Conducting more trials increases the reliability of the experiment by reducing the impact of random errors and providing more data.

Front

How can you identify the least popular item from a graph?

Back

The least popular item can be identified by looking for the lowest value or bar on the graph.

Front

What is the role of a hypothesis in an experiment?

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 (e.g., colors, textures), while quantitative data involves numbers and measurements (e.g., height, weight).

Front

Why is it important to have a control group in an experiment?

Back

A control group provides a baseline for comparison, helping to determine the effect of the independent variable.

Front

What does it mean to analyze data?

Back

Analyzing data involves examining and interpreting the results of an experiment to draw conclusions.

Front

What is a graph?

Back

A graph is a visual representation of data that helps to illustrate relationships between variables.
