What is a dependent variable?

• The variable that is manipulated in an experiment.

• The variable that is measured or observed in an experiment, which changes in response to the independent variable.

• The variable that remains constant throughout the experiment.

• The variable that is used to compare the effects of the independent variable.

What is a qualitative observation?

• An observation that describes qualities or characteristics without using numbers.

• An observation that uses numerical data to describe a phenomenon.

• An observation that is based on personal opinions and feelings.

• An observation that is made using scientific instruments.

What is the scientific method?

• A systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

• A random approach to solving problems without any structured process.

• A method used exclusively in laboratory settings for conducting experiments.

• A way to gather opinions and beliefs without any empirical evidence.

What is data collection?

• The process of gathering information and measurements during an experiment.

• A method of analyzing data after an experiment is completed.

• The act of storing data in a database for future use.

• A technique for presenting data visually in charts and graphs.

What is a conclusion in scientific research?

• A detailed explanation of the methodology used in the experiment.

• A summary of the results of an experiment and whether the hypothesis was supported or not.

• A list of all the materials used in the experiment.

• An introduction to the research problem being studied.

What is a scientific theory?

• A guess about how things work.

• A well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.

• A hypothesis that has not been tested.

What does it mean to analyze data?

• To collect data for future use.

• To examine and interpret data to draw conclusions or make decisions.

• To store data in a database.

• To visualize data using charts and graphs.

What is the Y-axis in a graph?

• The horizontal line on a graph that typically represents the independent variable.

• The vertical line on a graph that typically represents the dependent variable.

• A line that connects the data points in a graph.

• The line that represents the average value of the data.

What is the X-axis in a graph?

• The vertical line on a graph that typically represents the dependent variable.

• The horizontal line on a graph that typically represents the independent variable.

• A line that connects the origin to the point of interest on the graph.

• A line that represents the average value of the data points.
