What is run chart and control chart?
A run chart is the simplest of charts. It is a single line plotting some value over time. A control chart also plots a single line of data over time. However, control charts include upper and lower control limit lines with a centerline.
What can't a run chart tell you?
A run chart is a line graph of data plotted over time. By collecting and charting data over time, you can find trends or patterns in the process. Because they do not use control limits, run charts cannot tell you if a process is stable.

Who invented run charts?
Walter Shewart theorised as far back as in 1931 that the way to improve any process was to reduce the variation, and when feasible, to move the entire process in the desired direction. He distinguished two types of variation, special cause and common cause variation.
What is the Centre line in a run chart?
A run chart shows a measurement on the y-axis plotted over time (on the x-axis). A centre line (CL) is drawn at the median. The median is simply the 50th percentile measurement (ie, the middle data point when all the measurements are arranged in value order). The median is often written as X.
What is a non random pattern?
Cyclical Pattern: A cyclical pattern is defined as a predictive situation in which data points increase and decrease the process mean in a manner which is repetitive. In the case of control charts, cyclical patterns signify special cause variation because they are not random.

What does control charts distinguish between?
The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. These lines are determined from historical data.

A new run begins with the next plotted point. This test detects two types of nonrandom behavior: mixtures and clusters. If the p-value for mixtures is less than 0.05, you may have mixtures in your data. In this chart, the mixture may indicate that the data come from different processes.
