Data that are qualitative are always-

• described in words
• represented in numbers
• repeated for verification
• the most accurate type of data

• hold the test tube at its opening with at least two fingers
• keep the test tube closed with a rubber stopper

A hypothesis is a statement that-

• can be tested
• is almost always true
• is almost always false
• is the same as a theory

Mr. S. sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp.  Identify the constant.

• distance traveled by the ball
• height of the ramp
• mass of the ball
• weight of the ball
