Science and the Scientific Method Quiz

What is NOT a difference between quantitative and qualitative data?

• Quantitative data involves characteristics that cannot be counted

• Quantitative data are obtained by counting or measuring

• Qualitative data can include descriptions and interviews

• Quantitative data are numbers

What is the goal of science?

• To ignore events in the natural world

• To investigate and understand the natural world

• To make random predictions

• To control the natural world

What is the first step in the scientific method?

• Form a hypothesis

• Design a controlled experiment

• Observation / Asking a Question

• Record and analyze results

What is a hypothesis?

• A scientific method

• A proven fact

• A theory supported by much evidence

• A possible explanation for a set of observations

What is the independent variable in an experiment?

• The variable that is being tested

• The data we collect during the experiment

• The one observed during the experiment

• The variable that is deliberately changed by the scientist

Why is it important to have a large sample size in any experiment?

• To make the experiment more expensive

• To get a true picture of the results

• To make the experiment more time-consuming

• To make the experiment more complicated

What is the importance of the control in an experiment?

• It shows what will happen when the experimental factor is omitted

• It makes the experiment more interesting

• It has no importance in an experiment

• It makes the experiment more complicated

What is the difference between a theory and a hypothesis?

• A theory is a possible explanation, a hypothesis is a scientific method

• A theory is an educated guess, a hypothesis is a broad statement

• A hypothesis is testable through observations, a theory is a broad statement based on many experiments

• A hypothesis is supported by much evidence, a theory is a proven fact

Why is it important to repeat the experiment many times?

• To make the experiment more complicated

• To see if the same results are obtained each time

• To make the experiment more expensive

• To make the experiment more time-consuming

Why is it so important that a scientist accurately describes the procedure used in the experiment?

• To make the experiment more complicated

• To make the experiment more interesting

• To allow other scientists to repeat the experiment and verify the results

• To make the experiment more expensive
