Not quite remember

I easily remember

Communication in biology which involving graph

The relationship between the manipulated variable and responding variable can be illustrated in the form of a graph

Types of graph

Line graphs, bar charts and histograms.

General method of drawing a graph (1)

The responding variable is represented by the vertical axis (y-axis) and the manipulated variable is represented by the horizontal axis (x-axis)

General method of drawing a graph (2)

The scaling on the axis must be uniform

General method of drawing a graph (3)

Mark the points with an appropriate symbol such as ‘x'

General method of drawing a graph (4)

Title the graph: “Graph (responding variable) versus (manipulated variable)”

A bar chart

Presents data using vertical bars that are not attached to each other

Method of drawing a bar chart (1)

Draw two axes, the horizontal axis/X to represent the manipulated variable and the vertical axis/Y to represent the responding variable

Method of drawing a bar chart (2)

Each width of the bar needs to be uniform

Method of drawing a bar chart (3)

The bar height depends on the frequency of the data
