Below are statements about standard error. State exactly two that are true. As long as sample size is at least 2, standard error is smaller than standard deviation If sample size is increased, standard error is also decreased. standard error measures the variability in the sample data. in a confidence interval, when standard error is increased, the margin of error is increased.

Which of the following statements about sample size is true? a. A rule of thumb is to include at least two members from every subgroup to be analyzed. b. If the sample size is very small, a judgmental sample may be more reliable and representative than a probability sample. c. The determination of sample size should not involve cost. d. Low sampling costs do not justify a larger sample. e. None of the above.
