Question

question 14
what happens to the standard error of m if sample size is equal to 1?
a it increases to 1
b it decreases to 1
c it equals the standard deviation
d it becomes zero

Explanation:

The formula for the standard error of the mean \(M\) is \(SE = \frac{\sigma}{\sqrt{n}}\), where \(\sigma\) is the population standard deviation and \(n\) is the sample size. When \(n = 1\), substituting into the formula gives \(SE=\frac{\sigma}{\sqrt{1}}=\sigma\).

Answer:

C. it equals the standard deviation
