What is a confidence interval graph called?
Error bars are graphical representations of the variability of data and used on graphs to indicate the error or uncertainty in a reported measurement. Error bars often represent one standard deviation of uncertainty, one standard error, or a particular confidence interval (e.g., a 95% interval).
What are graphs called?
The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things. You would use: Bar graphs to show numbers that are independent of each other.
What do the horizontal lines on a forest plot represent?
Each horizontal line put onto a forest plot represents a separate study being analysed. In Figure 3, three studies are represented. Each study ‘result’ has two components to it: A point estimate of the study result represented by a black box. This black box also gives a representation of the size of the study.
What does it mean when two lines cross on a graph?
The point where two lines on a graph cross is called an intersection point. The other important term to know is slope. The slope tells us how steep a line on a graph is as we move from one point on the line to another point on the line.
What does the 95% confidence interval on a diamond mean?
If you drew a vertical line through the vertical points of the diamond, that represents the point estimate of the averaged studies. The horizontal points of the diamond represent the 95% confidence interval of this combined point estimate.
What is the horizontal axis of a statistic?
The horizontal axis usually represents the statistic the studies being profiled show. This could either be a ‘relative’ statistic like an odds ratio (OR) or a relative risk (RR). Or the statistics being used might be an ‘absolute’ one such as Absolute Risk Reduction (ARR) or Standardised Mean Difference (SMD).
