The formula for the standard error is:
A) $\sigma _ { M } = \sigma / \sqrt { N }$
B) $\sigma _ { S } = \mu / \sqrt { N }$
C) $\sigma _ { M } = \sum / N$
D) $\sigma _ { S } = \sum / ( N - 1 )$

The standard error of the mean (SEM) is calculated by dividing the standard deviation ($\sigma$) of the population by the square root of the sample size ($N$), which is accurately represented by option A: $\sigma _ { M } = \sigma / \sqrt { N }$.

The Formula for the Standard Error Is: A) σM=σ/N\sigma _ { M } = \sigma / \sqrt { N }σM​=σ/N​

The Formula for the Standard Error Is:
A) $\sigma _ { M } = \sigma / \sqrt { N }$
