How does the standard error affect the confidence interval?
- Larger standard error leads to a narrower interval
- Larger standard error leads to a skewed interval
- Larger standard error leads to a wider interval
- Standard error does not affect the confidence interval
Larger standard error leads to a wider confidence interval. The standard error measures the variability in the sampling distribution and a larger standard error suggests more variability, which in turn leads to less precise estimates and wider intervals.
