What is the formula in finding the margin of error in slovins formula if the sample size and the population is given?
yes
What is the formula to calculate size of a sample?
by using the capture-recapture method which gives you the total size of organisms in a population.
Formula for calculating work sampling?
Calculating the Sample Size The sample size, in this case, refers to the number of children to be included in the survey. Step 1: Base Sample-size Calculation The appropriate sample size for a population-based survey is determined largely by three factors: (i) the estimated prevalence of the variable of interest - chronic malnutrition in this instance, (ii) the desired level of confidence and (iii) the acceptable margin of error. For a survey design based on a simple random sample, the sample size required can be calculated according to the following formula. Formula:n= t² x p(1-p)m²Description: n = required sample sizet = confidence level at 95% (standard value of 1.96)p = estimated prevalence of malnutrition in the project aream = margin of error at 5% (standard value of 0.05) Example In the Al Haouz project in Morocco, it has been estimated that roughly 30% (0.3) of the children in the project area suffer from chronic malnutrition. This figure has been taken from national statistics on malnutrition in rural areas. Use of the standard values listed above provides the following calculation. Calculation: n= 1.96² x .3(1-.3).05²n = 3.8416 x .21.0025n = .8068 .0025 n = 322.72 ~ 323Calculating the Sample Size The sample size, in this case, refers to the number of children to be included in the survey.

Who is the statistician named slovin?
he was the one who introduced the slovin's formula, the estimated sample size given the population size and margin of error
What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.

What is Slovin's formula?
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).
What are sloven's formula in st atistics?
n=N/1+Ne2 sample size= population size/ 1+ population size* (error margin)2
What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
What is the Formula for sample deviation?
I believe you want the equation to calculate the standard deviation of a sample. The equation is: s = square root[ sum from i =1 to n of (xi- xbar)/(n-1)] where xbar is the average of values of the sample and n = size of sample.
Why does the effect-size calculation use standard deviation rather than standard error?
The goal is to disregard the influence of sample size. When calculating Cohen's d, we use the standard deviation in teh denominator, not the standard error.
How To Determine Sample Size?
I've included a couple of links. Statistical theory can never tell you how many samples you must take, all it can tell you the expected error that your sample should have given the variability of the data. Worked in reverse, you provide an expected error and the variability of the data, and statistical theory can tell you the corresponding sample size. The calculation methodology is given on the related links.
What is the difference between sample size and sample unit?
sample size is the specific size of a thing like the how long or wide. while sample unit is the whole thing not referring to specific number size.
