Safety Data Sheet

6 things required when making a graph?

1. Caption: Provides details about the graph, always placed at the bottom.

2. Label x and y axes: Clearly indicate what each axis represents.

3. Data points: Use a scatter plot to represent individual data points accurately.

4. Legend: Clarifies symbols/colors used in the graph (note: 'legend' is the correct spelling).

5. Slope + R²: Include these metrics when creating graphs digitally to show trends.

6. Uncertainties: Incorporate error bars to represent data variability.

What does N/DV stand for?

Non-Dependant Variable (Independant variable, x)

What does DV stand for?

Dependant Variable (y)
