The standard error is a measure of dispersion for a sampling distribution. It represents the standard deviation of the distribution of the sample means or proportions. This is different from the standard deviation of the raw data, which measures the spread of individual data points around the mean. The sampling frame is the list of individuals or units from which a sample is drawn. The sampling interval is the distance between items in the population that are selected for the sample. Therefore, neither A nor D are appropriate choices.
