Fig. 4 Responds of tree species richness to environmental factors. The solid line shows the estimations of tree richness, and the dashed lines indicate 95% confidence interval.
Not only it is painfully hard to account for all the variables that could possibly impact the project, but also the confidence interval itself can be little more than an educated guess.
Increasing the desired confidence level will widen the confidence interval.
In the final post hoc test of 21-year-old confidence, the normal distribution (95% confidence interval) level is lower than other ages.
All subjects from 13 primary schools with high morbidity were bled to study the effect on preventing lts The protective rate of the vaccine was 98.1%,the 95% low confidence interval is 83.5%.
Confidence limits are the upper and lower limits of the confidence interval.
The prevalence rate of smear-positive tuberculosis was 145 per 100 000 (95% confidence interval: 110–180) assuming no tuberculosis in persons aged15 years.
Point prevalence estimates, 95% confidence intervals and design effects were calculated.
You should also try to include the margin of error (often called the confidence interval) because it indicates the reliability of the evidence.
When an estimate is produced, it usually includes a confidence interval of some kind regarding its precision.
Sample size formulae that control the width of confidence interval with a certain confidence level are proposed.
The unintentional-fall-related mortality rate (MR) per 100 000 population was 14.5 (99% confidence interval, CI: 13.7–15.4).
It is the best general technique for producing confidence intervals.
The semiquantitative slide agglutination and single-tube Widal tests had positive predictive values (PPVs) of 25.0% (95% confidence interval, CI: 0.6–80.6) and 20.0% (95% CI: 2.5–55.6), respectively.
