How do I use Slovin’s formula in Excel?
1. Slovin’s Formula. – is used to calculate the sample size (n) given the population size (N) and a margin of error (e). -It is computed as n = N / (1+Ne2).
How do you find the sample size for an unknown population in Excel?
How to Find a Sample Size Given a Confidence Level and Width (unknown population standard deviation)
- za/2: Divide the confidence level by two, and look that area up in the z-table: .95 / 2 = 0.475.
- E (margin of error): Divide the given width by 2. 6% / 2.
- : use the given percentage. 41% = 0.41.
- : subtract. from 1.
How do you get sample size?
How to Calculate Sample Size
- Determine the population size (if known).
- Determine the confidence interval.
- Determine the confidence level.
- Determine the standard deviation (a standard deviation of 0.5 is a safe choice where the figure is unknown)
- Convert the confidence level into a Z-Score.
What is Krejcie Morgan formula?
b = (100000 – 10000)/(384 – 373) = 8181. S = 384 + (900000 : 8181)
What is Yamane’s formula?
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.
Why is Slovin’s formula used?
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.
How do you calculate sample size without population size?
Popular Answers (1) For sample size calculation of unknown population size, you can use the following formula: n= z2. [p*q]/d2), which is used to calculate the sample size of a qualitative variable in prevalence or cross-sectional studies.
Why do we use Krejcie and Morgan table?
The ever increasing need for a representative statistical sample in empirical research has created the demand for an effective method of determining sample size. To address the existing gap, Krejcie & Morgan (1970) came up with a table for determining sample size for a given population for easy reference.
What is Cochran’s sample size formula?
Cochran Formula (Cochran, 1977) = sample size = the population proportion ( = 0.1) = acceptable sampling error ( = 0.05) = value at reliability level or significance level.
What is the sample size of 200 population?
