Study Notes

General Graphing Rules

Every graph must have a clear title reflecting the data represented.
Label both axes: the x-axis for the independent variable and the y-axis for the dependent variable.
Determine the range of data to ensure the graph is appropriately sized for variability in values.
A key may be necessary to clarify colors or symbols in the graph.

Bar Graph

Suitable for comparing different groups or tracking changes over time.
Ideal when data is categorized, with spaces included between the bars to indicate distinct groups.

Histograms

Used for representing continuous data rather than categorized data.
No spaces are present between bars, highlighting the continuous nature of the data.

Line Graph

Effective for illustrating changes over time, each data point is connected to show trends.
Provides a visual representation of data progression across intervals.

Scatter Plot

Utilized to examine potential relationships between two variables.
Individual data points are plotted, and a best fit line may help illustrate correlations.

Pie Graph

Best for comparing parts to a whole, showing the size of each category in relation to the total.
Each slice represents a proportion of the total dataset, making it visually representative of percentages.
