Scientific Method Ag. Science

What is the first step of the Scientific Method?

• Hypothesis

• Experiment

• Drawing a conclusion

• Observation

Data that we observe with our senses is known as:

• Qualitative

• Quantative

• Results

• Hypothesis

Data that involves measurements and will always be in numerical values is known as:

• Prediction

• Double- blind testing

• Qualitative

• Quantitative

A factor that is changed in an experiment is known as

• Dependent factor

• Independent factor

• Controlled factor

• Observation

Describes the size and direction of a relationship between two or more variables

• Data

• Hypothesis

• Correlation coefficient

• Causation

The correlation coefficient of the the graph would be

• +2

• -1

• 0

• +1

Select which best describes Double Blind Testing

• The tester knows which group is the experiment group and control group

• The tester does not know who is the experimental group or the control group

• The tester decides the experiment group

• the tester decides the control group

Primary data is .....

• data collected by a scientist during an experiment

• data gathered during research of scientific journals

• data that is always in numerical form

• the first results from an experiment

Accuracy is....

• how close a measurement is to the true value

• how close the measurements are to each other

• how well a scientist uses their equipment

Consistent, repeatable error caused by faulty measuring instruments are known as

• Statistical uncertainties

• Correlation coefficient

• Systematic uncertainties

• Causation
