Individual value plot overview
An Individual Value plot is a statistical tool that displays
the performance or behavior of individual data points in a dataset. This plot generally emphasizes variation and trends in quality management, process control, and exploratory data analysis.
- For
every data point, the graph displays raw values without aggregation. The
approach is more detailed about variability and distribution in the data.
- It
is common for the x-axis to show different groups so we can observe the patterns of how the data is distributed between groups.
- This plot is very similar to a box plot. The major difference is that in a box plot, only the summarized data, such as median and quartiles, are shown, while in an individual value plot, each raw data point is also shown.
Application | Description |
Variability Understanding | It displays all data points so that the variations and outliers in the data set can be determined, thereby giving insight into inconsistencies or errors. |
Trend Analysis | Plotting the data over time or sequence helps observe trends, patterns, or shifts, which can help guide decisions. The x-axis, in this case, could be weeks, months, etc. |
Identifying Outliers | The Individual value plot easily identifies anomalies, outliers, or deviations that need further analysis. |
Presentation Simplification | Since it avoids aggregation (for example, means or medians), it allows stakeholders to understand the whole dataset without losing critical information. |
