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., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

Why is it important to change only one variable in an experiment?

Back

Changing only one variable helps to isolate the effects of that variable on the outcome, making it easier to determine cause and effect.

Front

What is the scientific method?

Back

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

Front

What is a graph used for in scientific experiments?

Back

Graphs visually represent data, making it easier to identify trends, patterns, and relationships between variables.

Front

What does it mean to analyze data?

Back

To examine and interpret data to draw conclusions or make decisions based on the results of an experiment.

Front

What is a conclusion in the context of an experiment?

Back

A summary of the results of an experiment, discussing whether the hypothesis was supported or not.
