In a hypothesis written in the "If, then" format, which variable comes first?

• Independent
• Dependent

In a hypothesis written in the "If, then" format, which variable comes second?

• Independent
• Dependent

The step of the scientific method that would come after testing is:

• Inferencing
• Hypothesizing
• Peer Review
• Analyzing Data

The easy way to pick out an experiments responding (DV) variable is to look for:

• What was purposefully changed
• Number of trials
• What's being measured
• The test group

The test group gets its name because this scientific variable is applied to this group:

• Manipulated
• Responding
• Dependent

The control group , or the normal group, is needed for:

• Keeping aspects of experiment constant

• Comparison

• Hypothesis formation

• Application of the manipulated variable

Experiments include many trials, since:

• It's fun

• Scientists like to stay busy

• More trials ensure the hypothesis is ALWAYS correct

• More trials increase accuracy of results

A good experiment will yield accurate results if it has:

• A really strong hypothesis
• Only one manipulated variable
• 1 or 2 trials maximum
• Two separate responding variables.
