what is the formula of sample
The formula for calculating the sample is typically represented as:
Sample = X / N
Where:
X = Sum of all values in the sample
N = Number of values in the sample
The formula for a sample depends on what you are referring to. In statistics, a sample refers to a smaller subset of a whole population. To calculate the formula for a simple random sample, you can use the following formula:
n = N / (1 + N * e^2)
Where:
- n is the sample size
- N is the population size
- e is the level of precision or desired margin of error
This formula helps determine the appropriate sample size needed to estimate a population parameter with a desired level of precision.
