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.
