The standard formula for calculating the sample size is:Sample Size Formula = [z2 * p(1-p)] / e2 / 1 + [z2 * p(1-p)] / e2 * N]Where,N is the population size z is the z-score e is the margin of error p is the standard of deviation...

Calculation of the Sample Size Sample size based on confidence intervals: In calculating the sample size, we are interested in calculating the population parameter. Thus, we should determine the confidence intervals, so that all the values of the sample lie within that interval range. Sample Siz...
Thus, the formula for calculating the p-value by calculating the z value is given by: z=p^−p0p0(1−p0)√nz=p^−p0p0(1−p0)n Where p^p^is Sample Proportion p0p0is the Assumed Population Proportion in the Null Hypothesis ...
The final step is to divide the current stock price of the company by the book value per share that you found in step two. You do this by dividing the share price by the book value per share to find the price to book ratio. The formula for calculating the P/B ratio would look li...
The formulas for calculating standard error along with examples are provided below. Standard Error Formula: Mean The standard error of mean can be calculated from a sampling distribution of means. This means that multiple samples were taken from the population and the means from each sample are ...

The equation for calculating standard deviation also includes degrees of freedom. Standard deviation is a statistical value that measures data dispersion in a sample or population. When determining the standard deviation for a sample, use {eq}n-1 {/eq} as the degrees of freedom. This helps asse...
