    Sampling and Sampling Methods There are many research questions we would like to answer that involve populations that are too large to consider learning about every member of the population. How have wages of European workers changed over the past ten years? Questions such as this are important in understanding the world around us‚ yet it would be impractical‚ if not impossible‚ to measure the wages of all European workers. Generally‚ in answering such questions‚ social scientists examine a fraction

    Sampling is the use of a subset of the population to represent the whole population. Probability sampling‚ or random sampling‚ is a sampling technique in which the probability of getting any particular sample may be calculated. Nonprobability sampling does not meet this criterion and should be used with caution. Nonprobability sampling techniques cannot be used to infer from the sample to the general population. The advantage of nonprobability sampling is its lower cost compared to probability sampling

    SAMPLING TECHINIQUE PROBABILITY SAMPLING Having chosen a suitable sampling frame and established the actual sample size required‚ you need to select the most appropriate sampling technique to obtain a representative sample. The basic principle of probability sampling is that elements are randomly selected in a population. This ensures that bias is avoided in the identification of the elements. It is an efficient method of selecting elements which may have varied characteristics‚ as the process

    Simple random sample (SRS) In statistics‚ a simple random sample from a population is a sample chosen randomly‚ so that each possible sample has the same probability of being chosen. One consequence is that each member of the population has the same probability of being chosen as any other. In small populations such sampling is typically done "without replacement"‚ i.e.‚ one deliberately avoids choosing any member of the population more than once. Although simple random sampling can be conducted

    2010 Graham Elliott. All Rights Reserved. Sampling We are now putting all of the pieces together. Considering each observation xi as an outcome from a random variable Xi ‚ we have that functions g(x1 ; x2 ; :::; xn ) are draws from the random variable Pn g(X1 ; X2 ; :::; Xn ): For 120a the function we are interested in is the sample mean — g(x1 ; x2 ; :::; xn ) = n1 i=1 xi : In this chapter we work with this function for distributions with many random variables. 1 From the Text Question 1.
