Nature of Science Practice

What is a variable in an experiment?

• A variable is a constant factor that does not change during an experiment.

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

• A variable is the outcome that is measured in an experiment.

• A variable is a hypothesis that is tested in an experiment.

What is a sample in research?

• A sample is a subset of a population used to represent the entire group in research.

• A sample is the entire population being studied.

• A sample is a random selection of data points from a dataset.

• A sample is a method of collecting data from multiple sources.

What is a Bar Graph used for?

• To display data in a circular format

• To compare different groups or categories

• To show trends over time

• To represent data in a three-dimensional space

What is an experiment?

• A method to collect data without a hypothesis.

• A procedure carried out to support, refute, or validate a hypothesis.

• A way to analyze past events without testing.

• A technique used only in scientific research.

What is observational research?

• A type of research where the researcher manipulates variables to see the effects.

• A type of research where the researcher observes and records behavior without manipulating any variables.

• A method of research that relies solely on surveys and questionnaires.

• A research approach that focuses on experimental and controlled conditions.

What is an Inference?

• A statement that is always true

• A conclusion drawn from evidence and reasoning

• A fact that can be proven

• An assumption made without evidence

What is a control group?

• A group that receives the treatment or intervention in an experiment.

• A group in an experiment that does not receive the treatment or intervention, used as a benchmark to measure how the other tested subjects do.

• A group that is randomly selected from the population to participate in the experiment.

• A group that is used to manipulate the variables in an experiment.

What is a scientific theory?

• A scientific theory is a guess about how things work.

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

• A scientific theory is an untested hypothesis.

• A scientific theory is a personal belief about the universe.

What is data collection?

• Data collection is the process of gathering and measuring information on variables of interest in a systematic way.

• Data collection is the act of analyzing data to draw conclusions.

• Data collection is the method of storing data in a database.

• Data collection is the process of deleting unnecessary data from a system.

What is the scientific method?

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

• A method used exclusively in laboratory settings to conduct experiments.

• A way to prove theories without the need for evidence.

• A technique for memorizing information quickly.
