Data Through Pictures

The scale tells us what each symbol represents, Count all symbols and multiply by the scale value, Half symbols can represent half the scale value, The title tells us what data is being shown

In pictographs: Scale shows symbol value, total = symbols × scale, symbols can be partial, and titles describe the data. Symbols don't always represent 1 item - they represent the scale value.

Bars can be drawn horizontally or vertically, The length/height of bars shows the quantity, Axes have labels to show what is being measured, Bar graphs are good for comparing different categories

Bar graphs can be horizontal or vertical, bar size shows quantity, axes need labels, and they're great for comparisons. Bars can be different colors.

40 children

Oranges have 5 symbols. Each symbol represents 8 children. Total children who like oranges: 5 × 8 = 40 children.

Horizontal axis (x-axis)

In a typical vertical bar graph, the horizontal axis (x-axis) shows the categories (like subjects), while the vertical axis (y-axis) shows the values (like scores).
