Standard Error

A standard error is the standard deviation of the sampling distribution of a statistic. Standard error is a statistical term that measures the accuracy with which a sample represents a population. In statistics, samples mean deviates from the actual mean of a population; this deviation is the standard error.
 

Method (i) Sample size (n) is calculated through margin error formula:


Standard Error of the Mean

The Standard Error of the Mean (SEM) of the population of individual male weighed 180 £, Standard Deviation (σ - SD), 25 £ and sample size (n), 10

Formula: SEM = σ / √ n

Solve for SE = 25 / √ 10 = 25 / 3.16 = 7.91

The Standard Error of the Mean (SEM) of the population of individual male weighed 180 £ and Standard Deviation (σ - SD), 25 £ was 7.91
