Tables and Graphing

Tables and Graphs

Tables and graphs are visual representations. They are used to organise information to show patterns and relationships. A graph shows this information by representing it as a shape. Researchers and scientists often use tables and graphs to report findings from their research.

Creating tables in Science

Rules for creating tables in Science:

1. Table should be enclosed

2. Table should be completed in pencil

3. Units should be included in the heading in brackets

4. A table should include a title

Creating Graphs in Science:

Graphs can then be constructed from the table to make it even easier to see patterns in the data.
Pie charts are useful for showing the parts that make up a whole. For example, a pie chart can be used to show the percentages of different substances in the Earth’s crust.
Bar and column graphs are used to display data that can be placed in categories. For example, a bar graph can be used to show the number of students in a class with a particular hair colour.
Line graphs are often used to represent continuous or connected data. A line graph is used to show how a measurement changes. For example, line graphs could be used to show how quickly a plant grows over time.
CUTLASS rules are used when graphing data (Crosses, Units, Title, Line of best fit, Axes labelled, Scale correct for each axis, Size appropriate to grid)

Line of Best Fit

Data plotted on a line graph might not form perfect straight lines or curves.
This is when a line of best fit is used.
These make patterns in the data easier to see.
They also allow you to predict missing measurements.
Line graphs can also be extrapolated when a line is extended beyond its final value.

Describing Patterns in Data

Graphs that produce straight lines or curves indicate a pattern or relationship between the variables you tested.
