What is the basic idea of dot density mapping? correct answers Visually display density of a variable over an area through the use of representative dots. Do dot maps use derived data or totals? correct answers TOTALS Map readers tend to underestimate the number/density of dots. Is it possible to correct this? correct answers It is possible, but because the impact on the overall pattern is small, correction may not be necessary. What happens visually to a dot map if the data range is to...
