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
How do you solve using slovin formula?
Slovin's formula is used to determine the sample size needed for a population when you want to achieve a certain level of precision. The formula is: ( n = \frac{N}{1 + N(e^2)} ), where ( n ) is the sample size, ( N ) is the total population size, and ( e ) is the margin of error (expressed as a decimal). To use it, first define your population size and desired margin of error, then substitute these values into the formula to calculate the sample size. This approach helps ensure that your sample is representative of the larger population while minimizing sampling error.
What is the formula for a margin of 30 percent on 100.00?
{100 * (30 / 100)} + 100 = 130
How do you calculate break-even?

How do you calculate the Contribution margin ratio?
sales-variable cost= contribution
How do you calculate the average contribution margin?
Formula for calculating average Contribution margin Average contribution margin = total contribution margin / total number of units
What is the Excel formula for the selling price if you have cost and margin?
The selling price is the cost plus the margin. If you know the margin as a fixed value and the cost was in cell A2 and the margin in B2, in C2 you could put the following formulas: =A2+B2 If the margin is a percentage of the cost and the margin is in B2, then the formula would be: =A2+A2*B2
What is Slovin's formula?
Slovin's formula is a mathematical formula used to determine the sample size needed for a survey or study. It takes into account the population size, desired level of confidence, and margin of error to calculate the appropriate sample size for a given study. It is commonly used in statistics and research to ensure accurate and reliable results.
How do you calculate contribution margin rate?
Formula for contribution margin ratio = Sales – Variable cost / Sales
What is the formula to calculate the gross margin?
The gross margin formula is gross profit divided by revenue. The gross profit and revenue amounts can be found by looking at a companies income statement.
What formula would you use to calculate the net profit margin?
You take the Earning before interest and taxes (EBIT)/sales=Operating profit margin
