Gallery: Confidence intervals
How to create your own
A simple graph that allows the presentation means and confidence intervals of several inter-related variables in an experiment.
Visual types:
This plot represents the outcome of a forecasting model a with simulated data set. The orange region show the confidence intervals for the forecast.
Visual types:
A chart used to summarise the findings of several studies about a common variable. It presents confidence intervals for each one of the studies considered. The example presents data on the effectiveness of silver sulfadiazine coating on venous catheters for preventing bacterial colonisation of the catheter and bloodstream infection.
Visual types:
A complex graph for presenting detailed population about population growth. It integrates other visualisation types: Histograms, representation of the quantile regressions, and boxplots for the residual values.
Visual types:
Funnel plot showing stroke admissions against national average
Funnel plot of re-admissions following stroke, for large acute or multi-service NHS Trusts in England. The funnel plot does not rank the data and it takes into account the increased variability of the smaller units.
Visual types:
Clustered bar chart with confidence intervals
Clustered bar chart showing inequalities in life expectancy for men and women who live in areas with different levels of deprivation (for Brighton and Hove).
Visual types:
Bar chart showing mortality from alcohol for males compared with females, with error limits.
Visual types:
Line chart showing actual teenage conception rates (green line) in comparison to trajectory (red circles), 1997 to 2010.
Visual types:
Joint Strategic Needs Assessment, Alcohol related harm admission rates (NI 39), wards benchmarked against the county average.
Visual types:
Health profile, benchmarking performance of an area on a range of variables against the regional average.
Visual types:
scorecard, confidence intervals, deviation bar graph, point chart, traffic light
Stacked column (with error limits and national baseline for benchmarking)
Performance of health trust in terms of the service provided by GPs.
Visual types:
bar chart, confidence intervals, range bar chart, traffic light
