A random sample of size 90 is selected from a population of over 2,000 students. The sample is measured on an achievement test and the mean score on the test is 79.5. The difference between the sample mean and the population mean is due to:

sampling bias

sampling error

the sampling fraction

sampling stratification

Sampling bias is variation caused by random fluctuation.
