Suppose your group makes several more measurements of the same quantity and then calculates the standard error on the mean again using all of your measurements. How would you expect the standard error to change?

Answer:

I would expect the standard error to decrease, because sample size increases.

Step-by-step explanation:

Standard error on the mean can be calculated using the equation:

[tex]\frac{s}{\sqrt{N}}[/tex]      where

  • s is the population standard deviation
  • N is the sample size

Therefore, if the group makes several more measurements then the sample size increases, which makes the standard error on the mean smaller.
