Match the following types of investigations with their definitions:

• A type of scientific investigations that uses Controlled Experiments to test hypothesis with and IV, DV, control group and experimental group

• Observational Investigation

• A type of scientific investigation where observations are made without interfering or altering anything. There is not hypothesis nor IV/DV

• Comparative Investigation

• A type of scientific investigation where 2 or more objects or phenomena are compared. There may be a hypothesis, but no 'control group'

• Experimental Investigation

What is Qualitative data?

• Data or observations that describes things because they cannot be expressed in numbers. Ex. smells, textures, etc.

• Data or observations expressed in numbers because they can be counted or measured

• A type of scientific investigation where observations are made without interfering or altering anything. There is not hypothesis nor IV/DV

• A type of scientific investigation where 2 or more objects or phenomena are compared. There may be a hypothesis, but no 'control group'

Match the following terms with their definitions:

• The factor changed by the scientist; the treatment given to the experimental group of test subjects in a controlled experiment; the “Cause”

• Dependent Variable

• Conducting your experiment on multiple test subjects or in multiple trials

• Controlled Variables (constants)

• A scientific experiment where only one variable is manipulated and tested at a time

• Independent Variable

• The response from the test subject being measured; the “Effect”

• Controlled Experiment

• All the factors that are kept the same between test groups to make a fair test

• Repetition

What is the purpose of replication in scientific experiments?

• To create new data

• To have another scientist conduct your experiment to compare and validate your results
