2.4 Data Collection Techniques and Data Analysis Review

Typically one square metre samples, selected for assessing the local distribution of plants or animals.

• Quadrat

• Transect

• Plot

• Grid

Organisms that do not move (plants or rocky shore species like barnacles).

• Sedentary

• Mobile

• Nomadic

• Migratory

How often a specific species (example: plants) occurs in a sample.

• Frequency

• Density

• Abundance

• Diversity

The cloudiness or haziness of water; the lower the visibility, the higher the (a)   .

• Clarity

• Turbidity

• Transparency

The counting of numbers of a specific organism present. (Can be low, with few individuals present - Opposite with higher presence) is known as (a)   .

• Density

• Abundance
• Scarcity

The selecting of a number of points within an area (random or systematically), determines how many points hit a specific plant species. This is called (a)   .

• Area Sampling

• Point Sampling
• Random Sampling

Data collected along a straight line (example: every plant that is touching the line is noted down) is referred to as (a)   .

• Line Sampling
• Transect Sampling

• Grid Sampling

T-shaped frame used to carry out point sampling. (The bar of the T has ten holes in it) ________.

• Point Quadrat

• Line Transect

• Belt Transect

• Random Quadrat

A trap used to sample populations of insects that are active on the ground. (cup or beaker used to check) ________.

• Pitfall Traps

• Light Traps

• Sticky Traps

• Sweep Nets

Nets that are mounted on a pole. (used to collect insects and other invertebrates from long grass) ________.

• Sweep Nets

• Fishing Nets

• Butterfly Nets

• Bird Nets
