Interval plot overview

Interval plot overview

An interval plot is a statistical graph that provides an idea about the variability in the data or compares the means/medians across groups. Data points or bars representing group means or medians are plotted with intervals, such as confidence intervals or standard error bars, that estimate the uncertainty or variability.

  1. The plot represents each group's mean or median of the data.
  2. Error bars, typically representing confidence intervals or standard errors, give an impression of the variability or reliability of the estimates.
  3. It enables easy comparison between different groups or categories.

Application
Description
Visualizing Uncertainty
Through intervals or SE bars, understand how much uncertainty/precision has crept in by confidence interval (CI).
Comparison between groups
Compare the central tendencies and assess differences for significance.
Hypothesis Testing
One can observe the overlap/nonoverlap of the intervals to know if the group's means/medians differ at a given statistical level.
Clear Presentation
Interval plots present statistical results intuitively and visually appealingly, making it easier to communicate findings.
Decision Making
The tool is useful in identifying significant differences, trends, or patterns, aiding decision-making in research and business scenarios.
