3. A lawn-care company wishes to estimate the density of a weed population in a park before spraying. The park measures 200 m 100 m. The technician randomly places four 2.0 m 1.0 m quadrats in the park, and finds weed counts of 22, 46, 32 and 40 plants in the 4 quadrats. Estimate the density of the population. A formal solution is required. 4.

Measures of Central Tendency and Dispersion. 1. Measure of central tendency: mean, median and mode from grouped and ungrouped data. For a set of data, we determine a quantity used to summarise the whole set of data. This quantity is termed a measure of central tendency. The most commonly used measures are mean, medium and mode. 1.1 mean. For ...
