What is slovin sampling?

What is slovin sampling?

Slovin’s formula. – is used to calculate the sample size (n) given the population size (N) and a margin of error (e). – it’s a random sampling technique formula to estimate sampling size. -It is computed as n = N / (1+Ne2).

Is Slovin’s formula A sampling techniques?

Slovin’s formula calculates the number of samples required when the population is too large to directly sample every member. Slovin’s formula works for simple random sampling.

What is the use of Slovin’s formula?

Slovin’s formula is used to calculate the sample size necessary to achieve a certain confidence interval when sampling a population. This formula is used when you don’t have enough information about a population’s behavior (or the distribution of a behavior) to otherwise know the appropriate sample size.

What is the Cochran formula?

The Cochran formula allows you to calculate an ideal sample size given a desired level of precision, desired confidence level, and the estimated proportion of the attribute present in the population. p is the (estimated) proportion of the population which has the attribute in question, q is 1 – p.

Who made slovin formula?

Taro Yamane is often credited with an identical formula. However, his formula was published several years after Slovin’s (in 1967).

Why do we use Yamane formula?

Yamane (1967:886) provides a simplified formula to calculate sample sizes. This formula was used to calculate the sample sizes in Tables 2 and 3 and is shown below.

What is the difference between N and N in Slovin’s formula?

Where: n = Number of samples, N = Total population and.

Is Slovin’s Formula reliable?

Abstract: In a number of research studies involving surveys, the so-called Slovin’s formula is used to determine the sample size. Unfortunately, many of these studies use the formula inappropriately, giving the wrong impression that it can be used in just about any sampling problem.

Which is better slovin or Cochran?

Cochran formula is use for large population that are heterogeneous in nature, but slovin’s formula is better for population which little or nothing is known. If every item in the population was the same we’d only need to extract a single item for it to be representative of the whole.

What is the sample size of 4500 population?

Determining Sample Size

Is Slovin and Yamane same?

Taro Yamane’s Formula Taro Yamane is often credited with an identical formula. However, his formula was published several years after Slovin’s (in 1967).

How do you calculate the sample size in Slovin’s formula?

Slovin’s Formula provides the sample size (​n​) using the known population size (​N​) and the acceptable error value (​e​). Fill the ​N​ and ​e​ values into the formula ​n​ = ​N​ ÷(1 + ​Ne​2). The resulting value of ​n​ equals the sample size to be used. When to Use Slovin’s Formula

What is Slovin’s formula used for?

Slovin’s Formula calculates the number of samples required when the population is too large to directly sample every member. Slovin’s formula works for simple random sampling. If the population to be sampled has obvious subgroups, Slovin’s formula could be applied to each individual group instead of the whole group.

How to find the source of sampling techniques by Cochran?

The best way to answer the question is to check the original publication. That is, check the original publication of Slovin (if it really existed) and Yamane(1967). The famous book on Sampling Techniques by Cochran has three editions: 1953, 1963, and 1977. The early editions of the book can be a good source.
