Confidence intervals explained |
|||||||||||||||
Researchers look at the "confidence levels" of percentages being compared to decide if there is a statistically significant difference between percentages. A statistically significant difference means that:
In this report, 95% confidence intervals will accompany each percentage in all figures and tables. This interval represents the range in which we are 95% confident the true percentage will fall within. In tables, the 95% confidence intervals will be written with the percentage, followed by the 95% confidence interval range in brackets (e.g., 25% (12.3, 32.4)). In figures, the 95% confidence interval is represented by vertical bars in each bar line. |
