The accuracy of a single sample mean

The difference between the mean and median

The variation in sample means from different samples

The consistency of sample means

To ensure accuracy

To demonstrate sampling variability

To find the exact population mean

To reduce calculation time

The exact population mean

The mode of the data

The distribution of sample means

The median of the data

The sample mean may vary from the population mean

The sample mean will be zero

The sample mean will be exactly half of the population mean

The sample mean will always equal the population mean
