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 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
