in TRENDABLE for Data Analysis
What is an Individuals Chart?
The simplest and most commonly used control chart is the Individuals or I-Chart. Each recorded observation is plotted on the chart in time order to evaluate the variation between consecutive samples. It is paired with the Moving Range MR-Chart to evaluate between observation variation. The centerline is the average of all observed values and the control limits are ±3 standard deviations from the average.
