ENV SCI 1.2.1-2

When it is not possible to conduct an experiment, scientists test their predictions by

• Examining correlations

• Using a control

• Testing for one variable

• Remaining skeptical

Risk is

• The collection of numerical data

• The probability that something wanted will happen

• The probability that something unwanted will happen

• A group of similar things of interest to a scientist

The classification and collection of data that are in the form of numbers is called

• Statistics

• Probability

• Distribution

• Mean

The group that doesn’t get the experimental treatment in an experiment is the

• Control group

• Experimental group

• Data

• Variable

In an experiment, the factor of interest is called the

• Control group

• Experimental group

• Hypothesis

• Variable

In a scientific investigation, it is important that the number of objects or events being sampled be

• equal to the mean number of objects or events not sampled.

• a guess of how likely an unwanted outcome will occur.

• equal to the total statistical population.

• large enough to give an accurate estimate for the whole population.

An example of a(n) ____________________ model is a flow chart showing how water moves between the atmosphere and Earth’s surface.
