Which of the following is best for showing monthly rainfall at a station?

Aa bar graph
Ba pie chart
Ca contour map
Da compass rose

Show the answer and working

Answer: A

Monthly rainfall → bar graph.

Trap B Confuses statistical maps and graphs: Dot map: each dot = a fixed quantity (distribution). Choropleth: shading by administrative area (density). Isopleth: lines joining equal values (isohyets, isotherms). Flow map: line width shows volume of movement. Proportional circles/bars: size proportional to value.

Trap C Map reading errors: Close contours = steep slope; wide = gentle. Gradient = vertical interval ÷ horizontal equivalent (same units). Four-figure grid ref: eastings first, then northings.

Trap D Picks a closely related feature or term: Learn related features as contrasting pairs: how each forms and what it looks like.
