Why do we sample and estimate populations?
The bottom line is it would be wasteful and foolish to use the entire population when a sample, drawn scientifically, provides accuracy in representing your population of interest. Assessing all individuals may be impossible, impractical, expensive or even inaccurate.
Which is the indirect biological counting method?
It would be almost impossible to accurately count every animal in a population. Indirect counting methods are used to give indices of the relative numbers. This involves looking for things such as nests, burrrows, skat, tracks etc. to estimate the population.
What is used to estimate the population parameter?
point estimate
What sample statistic is used to estimate a population parameter?
A point estimate is a single value (statistic) used to estimate a population value (parameter)true apex

Less prone to bias errors.
Explain the need to use sampling techniques to make population estimates when total counts cannot be made?
Sometimes a definite count of individuals within a population is not possible, the population may be constantly moving or distributed over a large area. In such cases, an estimate is made by counting small samples.
Counting the number of organisms in one area and multiplying to estimate the number in a larger area is called?
Population density is the counting of number of organisms in one area and multiplying to estimate the number in a larger area.

What is the direct population size of the chinchillidae?
The direct population size of the Chinchillidae family, which includes chinchillas, is difficult to determine as it varies depending on the specific species and their natural habitats. While some species have larger populations, others are endangered or critically endangered with smaller numbers. For example, the critically endangered Chilean chinchilla has an estimated population of only a few thousand individuals.
