When taking samples from a population and computing the proportion of eachâ sample, what factors should be considered?

(a)the sampling techniques that you use;

(b) the sample size you select;  

(c) the role of gatekeepers that influence access to your sample:

Explanation:

Sampling considerations refer to the desirable characteristics that should always be considered when selecting a sample so as to increase chances of correct estimation of population parameters.

The sampling strategy that you are following can raise a number of ethical issues that must be understood and overcome. When thinking about the impact of sampling strategies  you need to take these into account:

a)the sampling techniques that you use;

(b) the sample size you select;  

(c) the role of gatekeepers that influence access to your sample:

there is often only a small difference between what is legal and what is ethical when working with competitive intelligence..

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.
