Yamane's formula, 1967, is one of the common methods in survey research used to estimate an appropriate sample size for any given population with concern for precision and practicality [12]. This formula approximates the sample size based on the total size of a population and desired margin of error.
This paper proposes an adjustment to the margin of error in Yamane's (1967) formula to make it applicable for use in determining optimum sample size for both continuous and categorical...
Do you want to determine sample size in your project or thesis, here is the Taro Yamane Formula and 3 Calculations to determine Sample Size.
Formula: n = N / (1 + N * e 2) n: Sample size; N: Population size; e: Margin of error (as a decimal) This formula is known as Yamane's formula (1967) and is used to calculate sample size for a finite population.
TARO YAMANE METHOD. The Taro Yamane method for sample size calculation was formulated by the statistician Tara Yamane in 1967 to determine the sample size from a given population. Below is the mathematical illustration for the Taro Yamane method: n= N/ (1+N (e) 2) Where: n signifies the sample size. N signifies the population under study
The formula is: n = N / (1 + Ne^2). Here, “n” is the sample size, “N” is the population size, and “e” is the margin of error. By using Excel and the Taro Yamane formula, you can quickly figure out the right sample size for your research. This method makes your studies more efficient and accurate.
