Interpreting Graphs Notes: Graphs are used to present data in a picture format. Components of a good graph: 1. Title 2. Label each axis. Give units used 3. Determine a scale, (the numerical value for each square), that best fits the data.
Plot data correctly (x, y) • Conclusion/relationship -a complete sentence
Relationship: _________________________________________________
Vocabulary Variable- items being compared Interval scale- amount the axis increase by each line State a relationship- a sentence that explains how one variable affects the other.
Figure 1. Parts of a graph pH Affects Enzyme Activity Conclusion: As pH level increase the rate of enzyme activity decreases
Types of relationships Positive Negative As _x__ increased, _y_ increased As _x__ increased, _y_ decreased
No relationship No change/constant As _x_ changed , the _y_. stayed the same. There is no relationship between _x_ and _y_.
