What are the disadvantages of systematic sampling?
Disadvantages of systematic sampling: © The process of selection can interact with a hidden periodic trait within the population. If the sampling technique coincides with the periodicity of the trait, the sampling technique will no longer be random and representativeness of the sample is compromised.
How can an ecologist predict the size of a population without counting every organism in the population?
Through mark-and-recapture projects, direct observations, or targeted sampling, ecologists are able to determine the population of a particular species. This process is a scientific estimation of the population.
Is questionnaire probability sampling technique?
A questionnaire has little to do with sampling technique. Sampling technique is to do with who gets the questionnaire and that can be any sampling technique: the questionnaire can be sent to everyone (census), to a random sample, stratified random samples, to random samples in clusters, by quota or convenience. Or a pile of questionnaires can be left for respondents to pick up - self-selection.
What is the absolute value of the difference between the point estimate and the population parameter it estimates?
B. The sampling error
What is population sampling?
Population sampling is the process in which a group of individuals are selected to represent a population for the purpose of statistical analysis. Population sampling allows the analyzers to learn about a population without studying every individual in it.
Which sampling technique can assure that the profile of the sample matches the profile of the population?
Stratified sampling
What sampling technique will be the best for the large population size?
Clustered sampling.Clustered sampling.Clustered sampling.Clustered sampling.
How do ecologists measure population density?
By taking a sample of the entire population.
What is slovene's formula?

Sampling error refers to?
Sampling error occurs when the sampling protocol does not produce a representative sample. It may be that the sampling technique over represented a certain portion of the population, causing sample bias in the final study population.
How do you xxplain any two factors that affect the choice of a sampling technique?
Two factors that affect the choice of a sampling technique are the population size and the level of accuracy required. For large populations, it may be more practical to use a random sampling technique, while for small populations, a convenience sampling technique may be sufficient. Additionally, if high accuracy is required, a stratified sampling technique may be more appropriate to ensure representation of all subgroups within the population.
What is common sampling technique in communication system?
Random Sampling is the most common sampling technique
Why sampling needed?
Sampling is needed in order to determine the properties of a distribution or a population. Sampling allows the scientist to determine the variance in an estimate.
Which sampling technique is appropriate for voting behaviour of people?
stratified sampling technique

How can an ecologist ecologist measure population size?
Ecologists can estimate population size through methods such as mark-recapture, distance sampling, and census surveys. Mark-recapture involves capturing and marking individuals, releasing them, and then recapturing a sample to estimate total population size. Distance sampling involves estimating population size by observing and recording the distances to individuals from a specific vantage point. Census surveys involve conducting a thorough count of all individuals in a specific area.
