Why is a sample usually preferred over a census?
Less time and less cost for a sample.
Why is geometric progression preferred over arithmetic progression?
The question cannot be answered because it assumes something which is simply not true. There are some situations in which arithmetic progression is more appropriate and others in which geometric progression is more appropriate. Neither of them is "preferred".
What is the preferred method of solicitation when conducting simplified acquisitions over the micro purchase threshold?
The required sources of supplies and services can be found in:
Why pid is preferred over other controllers like pi and pd?
it because pid has the derivative part ,which will predict the disturbance .so helps in antisipating the errors & correcting them in advance.
What does a above a number mean in statistics?
The special character in your question didn't come through.If it was a horizontal bar then it implies the sample mean; for example, for a sample of 'x' values (usually numbered 1, 2, 3, ..., n) x with a bar over it would mean the statistical average or mean of these numbers.If the special character was a caret then it implies any of a variety of statistical estimators. For example, if you had assumed for some reason that the data had arisen from a population with a Poisson distribution with parameter 'lambda' then you might see a Greek letter lambda with a caret over it to represent a formula for calculating a statistical estimate of that parameter.
Advantages of census over sample survey?
It is more accurate, unbiased and includes every item in the population, whereas sampling may be biased, and sampling is not totally representative.
Which type of language is preferred in research writing?
The preferred language in research writing is typically formal and objective. It is important to use precise and specific terminology, avoid biased or emotive language, and present information in a clear and concise manner. Additionally, passive voice is often preferred over active voice, and the use of first-person pronouns should be limited.
What is non-response bias?
One effect of non-response is that is reduces the sample size. This does not lead to wrong conclusions. Due to the smaller sample size, the precision of estimators will be smaller. The margins of error will be larger.A more serious effect of non-response is that it can be selective. This occurs if, due to non-response, specific groups are under- or over-represented in the survey. If these groups behave differently with respect to the survey variables, this causes estimators to be biased. To say it in other word: estimates are significantly too high or too low.

Estimator?
Cost estimators are vital to the financial success of manufacturers, builders, and businesses. It’s the responsibility of an estimator to accurately access and analyze the costs to complete any given project. Estimators must factor in the cost of equipment, materials, supplies, labor, profit margin, and unexpected events, such as shipping delays and weather. The vast majority of estimators work within the construction industry, however, many are employed by manufacturers and government agencies.Estimator TrainingBecause there is no formal degree for cost estimators, some companies prefer candidates with a strong work history or a bachelor’s degree in a related field. Candidates with a bachelor’s degrees in accounting, business, construction, economics, engineering and statistics have successfully become professional estimators. Many of these fields include cost estimating classes at the undergraduate level. Government agencies and some companies require estimators to complete a voluntary professional certification. Professional estimator certifications are issued by various organizations, including the American Society of Professional Estimators, the Association for the Advancement of Cost Engineering, and the Society of Cost Estimating and Analysis. To qualify for certification, estimators must pass a written exam and have two years of work experience as an estimator.Careers as an EstimatorApproximately 60% of estimators work within the construction industry with the remainder employed by manufacturers. The most successful cost estimators can be promoted to project manager or go on to an independent consulting career. Due to the nature of the industry, estimators are required to work in the office and in the field. After performing an on-site analysis, estimators return to the office to prepare a full report and bid. In large companies, estimators may act as intermediaries between executives, subcontractors, and partners.Average Salary for EstimatorsOn average, cost estimators earn between $55,000 and $60,000 annually depending on the industry. Estimators in entry-level positions earned more than $33,000 in 2008, however, the highest-paid estimators earned $94,000. Due to growth in the construction industry and the need for additional infrastructure, job openings for cost estimators are projected to grow rapidly over the next decade. According to the Bureau of Labor Statistics, more than 55,000 new job openings for cost estimators are expected by 2018.
