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.
