3. Types of graphs Graphs: is a visual way to organize data
Line Graph: often used to show trends in data over time
Types of graphs

4. Bar graph/ Pie graph Bar graph: compares groups of information
Pie graph: is a circular graph that shows how a whole is divided into percentages.

5. Scatterplot/ Line graph
scatterplot aka (XY graph): used to determine if 2 variables are related.
Commonly used in in science
Usually has an:
-Independent variable: the variable you believe might influence another variable
- Dependent variable: the variable that may be influenced by the independent variable.
Scatterplot/ Line graph

6. MIXES TUCS M: maximize your graph (use all of the graph paper)
IX: independent variable on x-axis (dependent variable on y-axis)
ES: equally spaced scale increments (start at 0)
T: title (y-variable vs. x-variable)
U: units and labels on both axes
CS: continuous smooth curves to connect the data points.

7. Identifying relationships between variables on a graph
Direct relationship: a relationship in which one variable increases with an increase in another variable.
Inverse relationship: a relationship in which one variable decreases when another variable increases.
No relationship: the graph looks like a collection of graphs, no pattern appears.
