Estimate a Population Parameter

Estimation is a mental process by which a quantitative order or care fors ar narrowed to a macrocosm parameter establish on the study collected from a ingest. The distributement of assess(s) to a tribe parameter based on a value of the equivalent stress statistic is c exclusivelyed estimation. In illative statistics, _ is called the align population call up and p is called the true population comparison. in that location are many another(prenominal)(prenominal) population parameters, such as the median, mode, variance, and threadbare deviation.The following are a few examples of estimation an auto party whitethorn urgency to depend the imply fuel consumption for a particular model of a car a manager may want to estimate the fairish cadence taken by refreshed employees to learn a joke the U. S. Census chest of drawers may want to square up the mean lodgment outlay per month incurred by households and the AWAH (Association of Wives of drenching Husba nds) may want to find the proportion (or percentage) of all husbands who are wet.The examples roughly estimating the mean fuel consumption, estimating the average time taken to learn a job by impertinent employees, and estimating the mean housing outlay per month incurred by households are illustrations of estimating the true population mean. The example about estimating the proportion (or percentage) of all husbands who are alcoholic is an illustration of estimating the true population proportion, p.This condition explains how to assign values to population parameters based on the values of seek statistics. For example, to estimate the mean time taken to learn a authorized job by current employees, the manager will take a adjudicate of new employees and understand the time taken by for each one of these employees to learn the job. Using this discipline, he or she will calculate the take mean, then, based on the value of he or she will assign certain values to _.As anot her example, to estimate the mean housing expenditure per month incurred by all households in the United States, the Census Bureau will take a sample of certain households, collect the information on the housing expenditure that each of these households incurs per month, and compute the value of the sample mean, Based on this value of the bureau will then assign values to the population mean, _. The sample statistic employ to estimate a population parameter is called an estimator.The estimation part involves the following steps. 1. Select a sample. 2. meet the required information from the members of the sample. 3. suppose the value of the sample statistic. 4. Assign value(s) to the corresponding population parameter. Remember, the procedures to be mentioned supra assume that the sample taken is a simple haphazard sample. If the sample is not a simple random sample, then the procedures to be used to estimate a population mean or proportion convey more complex.Estimate a commu nity ParameterEstimation is a procedure by which a numerical value or values are assigned to a population parameter based on the information collected from a sample. The appointment of value(s) to a population parameter based on a value of the corresponding sample statistic is called estimation. In inferential statistics, _ is called the true population mean and p is called the true population proportion. There are many other population parameters, such as the median, mode, variance, and standard deviation.The following are a few examples of estimation an auto company may want to estimate the mean fuel consumption for a particular model of a car a manager may want to estimate the average time taken by new employees to learn a job the U. S. Census Bureau may want to find the mean housing expenditure per month incurred by households and the AWAH (Association of Wives of Alcoholic Husbands) may want to find the proportion (or percentage) of all husbands who are alcoholic.The examples a bout estimating the mean fuel consumption, estimating the average time taken to learn a job by new employees, and estimating the mean housing expenditure per month incurred by households are illustrations of estimating the true population mean. The example about estimating the proportion (or percentage) of all husbands who are alcoholic is an illustration of estimating the true population proportion, p.This article explains how to assign values to population parameters based on the values of sample statistics. For example, to estimate the mean time taken to learn a certain job by new employees, the manager will take a sample of new employees and record the time taken by each of these employees to learn the job. Using this information, he or she will calculate the sample mean, then, based on the value of he or she will assign certain values to _.As another example, to estimate the mean housing expenditure per month incurred by all households in the United States, the Census Bureau wi ll take a sample of certain households, collect the information on the housing expenditure that each of these households incurs per month, and compute the value of the sample mean, Based on this value of the bureau will then assign values to the population mean, _. The sample statistic used to estimate a population parameter is called an estimator.The estimation procedure involves the following steps. 1. Select a sample. 2. Collect the required information from the members of the sample. 3. Calculate the value of the sample statistic. 4. Assign value(s) to the corresponding population parameter. Remember, the procedures to be mentioned above assume that the sample taken is a simple random sample. If the sample is not a simple random sample, then the procedures to be used to estimate a population mean or proportion become more complex.
