Type II errors are more likely to occur when the sample size is inadequate. This is because Type II errors occur when the null hypothesis is true but the researcher fails to reject it. When the sample size is small, the researcher is less likely to have enough data to detect a statistically significant difference between the groups, even if one exists.
