To calculate the standard error, you need to divide the standard deviation by the square root of the sample size.

Question

To calculate the standard error, you need to divide the standard deviation by the square root of the sample size.

Standard Error = Standard Deviation / √(Sample Size)
Standard Error = 3.5 / √(5)
Standard Error = 3.5 / √5
Standard Error ≈ 3.5 / 2.24
Standard Error ≈ 1.56

Therefore, the standard error is approximately 1.56 when rounded to the nearest hundredth.

Answer 1

Remember that the standard error is a measure of the variability of a sample mean and represents how well the sample mean approximates the population mean.
