Sampling saves money by allowing researchers to gather the same answers from a sample that they would receive from the population. Sampling reduces the population into small manageable units. This type of correspondence between the sample and the larger population is most important when a researcher wants to know what proportion of the population has a certain characteristic like a particular opinion or a demographic feature. Use of sampling takes less time also. This is the reason why they are purposively chosen as subjects. Quadrats work well for observing changes to whole populations over time, including distribution patterns, nesting and overall health. When a statistic (a function) is being used for a specific purpose, it may be referred to by a name indicating its purpose: in descriptive statistics, a descriptive statistic is used to describe the data; in estimation theory, an estimator is used to estimate a parameter of the distribution (population); in statistical hypothesis testing, a test statistic is used to test a hypothesis.

In general, the larger the sample, the smaller the sampling Stratified sampling- she puts 50 into categories: high achieving smart kids, decently achieving kids, mediumly achieving kids, lower poorer achieving kids and clueless . Each sample drawn from the population has its own value of any statistic that is used to estimate this parameter. The main purpose of the creation and present-day use of multi-stage sampling is to avoid the problems of randomly sampling from a population that is larger than the researcher's resources can handle. To draw conclusions about populations from samples, we must use inferential statistics which enables us to determine a populations characteristics by directly observing only a portion (or sample) of the population. 57 0 obj <>/Filter/FlateDecode/ID[<84C45401CEA037BD5B83E6F52FD50082>]/Index[34 46]/Info 33 0 R/Length 109/Prev 143819/Root 35 0 R/Size 80/Type/XRef/W[1 3 1]>>stream Since the data collected under this method is limited but homogeneous, so more time could be spend on decision making.
