What is the number of individuals in a population called?
The number of individuals in the population is the population's size. If a population is small enough you will be able to determine the size by counting the individuals.
In order to determine the size of a sample the standard deviation of the population must be estimated To do this you can either take a pilot survey or it can be approximated based on a knowledge of?

What is one method the ecologists use to estimate the the size of a population?
survey

survey
What is the ideal sample size for a given population?
There is no "ideal" sample size for any given population, because polls and other statistical analysis forms depend on many factors, including what the survey is intended to show, who the target audience is, how much statistical error is permitted, and so on. The "Survey System" link, below, offers definitions and a couple of calculators to determine the best sample size for most purposes.

What is the size of a sample for a survey?
The population is every data point you intend to generalise the survey results to. The sample frame is those data points that you can pick from for the survey. The sample is which of these data points you actually survey, and the sample size is how many of those data points there are. For instance, if you have 700 students in a school, and you have access to 300 of them, and decide to give 30 of them a survey, the sample size is 30.
What are the four processes that determine population growth?
The four processes that determine population growth are birth rate, death rate, immigration, and emigration. Birth rate and immigration increase population size, while death rate and emigration decrease population size. These processes collectively determine whether a population grows, shrinks, or remains stable over time.
What determine the kind and size of population in the area?
How many of the same types of organisms live in that area .
What is the sample size of a survey?
The sample size of a survey refers to the number of individuals selected to participate in the survey. It is crucial in determining the reliability and accuracy of the survey results. A larger sample size generally leads to more statistically significant results.
What can one do with a sample size calculator?
According to the website Survey System's Creative Research Systems page, you can use a sample size calculator to determine how many people need to be interviewed in order to meet your target.
What is the most least invasive way to determine population size?
The least invasive way to determine population size is to use the sampling technique. If you are able to determine how many subjects are in a few small areas, you may be able to estimate how many are in the entire area. An example would be, if there are 10 people living in one apartment building, and there are a total of 50 apartment buildings in the complex, an estimate of your population size would be 500, assuming there are no empty apartments.
