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
