Interpretation for Figure AIn KFL&A in 2013 and 2014, 17.6*% (9.0, 31.7) of youth, 12 to 19 years, have smoked a whole cigarette, which is similar to Ontario, 14.4% (12.8, 16.1). In Ontario, the percentage of youth, 12 to 19 years, who have smoked a whole cigarette was decreasing over time. *Use with caution due to high variability |

Confidence intervals explained
Researchers look at the "confidence levels" of percentages being compared to decide if there is a statistically significant difference between percentages. If the 95% confidence intervals of two estimates do not overlap, there is considered to be a significant difference between the estimates. A statistically significant difference means that:
- the difference between two percentages is unlikely to have occurred by chance alone, and
- there is likely a true difference or change in the percentages.
In this report, 95% confidence intervals will accompany each percentage in all figures and tables. The true or actual percentage falls within the 95% confidence interval range 95 times out of 100. A wide confidence interval reflects a large amount of variability or imprecision. Usually, the larger the sample size, the narrower the confidence intervals. In tables, the 95% confidence intervals will be written with the percentage, followed by the 95% confidence interval range in brackets, e.g., 25.3% (12.3, 32.4). In figures, the 95% confidence interval are represented by error bars at the top of each bar (column).
