WebbThe first step in the analysis is to develop a point estimate for the population mean or proportion. Use this formula to estimate the population mean: Sample mean = x = Σx / n. where Σx is the sum of all the sample observations, and n is the number of sample observations. A proportion is a special case of the mean. Webb14 dec. 2024 · Slovin's formula calculates the number of samples required when the population is too large to directly sample every member. Slovin's formula works for …
