Three types of graphs for quantitative data

1. Bar chart

2. Histogram

3. Scatter graph

What is a bar chart used for? How must it be drawn?

Experimental research

IV-x-axis DV=y-axis

Either used to represent frequency or nominal data, categories=x-axis and frequency=y-axis→ columns do not touch and have equal width and spacing

What type of quantitive data is a histogram used to represent and how should it be drawn?

Frequency data e.g. interval or ordinal

Columns touch because each one forms a point on a related scale

Which type of quantitive data is a scatter graph used for?

Raw data

Shows a correlation between two variables
