This data type is non-numerical in nature.

• Qualitative Data

• Quantitive Data

The one factor that a scientist changes during an experiment.

• Controlled Variable

• Dependent Variable

• Independent Variable

Kayden conducted his science experiment 5 times to make sure he got the same results each time.

• Replication

• Repetition

Two scientists completed 250 trials of an experiment. They also ran a computer simulation. They discovered that the computer simulation of the experiment yielded different results than the experiment they had conducted. In science, which of the following is the best action the scientists should take next?

• They should repeat the experiment.

• They should ask another scientist to replicate the experiment.

• They should do nothing because the computer simulation is probably wrong.

• They should adjust the computer program so that the simulation matches their results.
