Intro to L.S

Observations Factual statements that describe a personal experience obtained through use of one or more of the senses.
Qualitative Observations Observations that determine quality, they are not measurable. Ex: Color, action, shape, texture, translucence.
Quantitative Observations Observations that determine quantity, they are measurable. Ex: size, sound, mass, volume, speed, pressure, humidity.
Manipulated (Independent) Variable The variable in an experiment that is purposely changed by the experimenter. Ex: Fish Exp. – Placing mirror against tank.
Responding (Dependent) Variable The variable that changes as a result of changing the manipulated variable. Ex: Fish Exp. – Fish’s behavior
Controlled Variable Variable that does not change, stays the same. Ex: Fish Exp. – Size of tank, water temp. type of fish.
Hypothesis A testable statement that shows the relationship between the manipulated and responding variables in an experiment, it often written as an if/then statement. If a hypothesis proves to be incorrect it can still add to scientific knowledge.
Conclusion A summary of the findings of an experiment that compares collected data to the hypothesis.
Control Group A group that does not have the manipulated variable applied so they can be compared to the group that does have the manipulated variable applied.
