What are the quality of a good estimator?
A "Good" estimator is the one which provides an estimate with the following qualities:Unbiasedness: An estimate is said to be an unbiased estimate of a given parameter when the expected value of that estimator can be shown to be equal to the parameter being estimated. For example, the mean of a sample is an unbiased estimate of the mean of the population from which the sample was drawn. Unbiasedness is a good quality for an estimate, since, in such a case, using weighted average of several estimates provides a better estimate than each one of those estimates. Therefore, unbiasedness allows us to upgrade our estimates. For example, if your estimates of the population mean µ are say, 10, and 11.2 from two independent samples of sizes 20, and 30 respectively, then a better estimate of the population mean µ based on both samples is [20 (10) + 30 (11.2)] (20 + 30) = 10.75.Consistency: The standard deviation of an estimate is called the standard error of that estimate. The larger the standard error the more error in your estimate. The standard deviation of an estimate is a commonly used index of the error entailed in estimating a population parameter based on the information in a random sample of size n from the entire population.An estimator is said to be "consistent" if increasing the sample size produces an estimate with smaller standard error. Therefore, your estimate is "consistent" with the sample size. That is, spending more money to obtain a larger sample produces a better estimate.Efficiency: An efficient estimate is one which has the smallest standard error among all unbiased estimators.The "best" estimator is the one which is the closest to the population parameter being estimated.
Advantages and disadvantages of primary and secondary sources of information?
Primary sources of information are great because they are first hand information from someone who was there. Secondary sources are based on primary sources, and may be biased.
The simultaneous distribution of information across different neural pathways is known as?
prallel processing
Can 50.4 be estimate?
Yes, 50.4 can be estimated. In this case, you would round it to the nearest whole number, which would be 50. This is a common estimation technique when dealing with decimal numbers.
Is it true that an estimate is based on known information?
An estimate is a "give or take" answer based on the knowledge that is known pertaining a certain subject
An estimate is not a guess because an estimate is based on?
Some previously held information, which is used to come to an estimate. A guess involves no previously held information.
What is an educated guess based on known information?
Conjecture
How can you estimate a company's profit without a profit and loss account?
You can take known information about the company and apply industry/regional standards. For example, if it is a retail store, you could estimate sales based on square footage and then estimate profit as a percentage of sales. If it is a service business, you could estimate income per productive employee, etc.
Most of the information that is known today about ancient cultures is based on?
objects from the cultures .
Is evolution called a theory?
Evolution is called a theory based on known researched information. When or if some of the information is found to be incorrect or if new information becomes availabe, the theory may be revised.
What is the definition of estimate?
An estimate is an approximate calculation of the value, number, quantity, or extent of something based on available information. It is not an exact measurement but rather a rough approximation.
What are insurance quotes?
An insurance quote is an estimate of the cost for an insurance policy. The estimate is based on the information that you give to the agent who is quoting the policy for you. For this reason it is imperative that you give them accurate information if you want to get an accurate quote back. If you tell the truth about your tickets, accidents, claims, residence, etc then the agent can give you back an accurate estimate of your cost for the policy.

How tall is till lindemann?
A good estimate based on photos of him next to other famous/well known people is around 6'1-6'2 feet tall.
What is an approximate number based on reasonable assumptions?
An approximate number is an estimate or rough calculation based on logical assumptions or available information. It is not precise but gives an idea of the expected value within an acceptable range of accuracy.
How does a calorie counter works?
Calorie counters work based on the information that you give them. Basically what it does is gives you a rough estimate of your calorie intake/ calories burned based on what foods you ate and how much and for how long you've worked out that day.
