Run charts trends
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. Run charts also provide tests for randomness that provide information about non-random variation due to trends, oscillation, mixtures, and clustering in your data. Such patterns indicate that the variation observed is due to special-cause variation. A run chart is a graphical display of data over time. Run charts are used to visually analyze processes according to time or sequential order. They are useful in assessing process stability, discovering patterns in data, and facilitating process diagnosis and appropriate improvement actions. Through analysis of a run chart, the following can be derived: changes / trends of the process over time. any pattern / cycle of the process. Examples of a run chart: progress of the project / processes / tasks (percentage completion over time) expenditure of the project. Plus: A run chart is easy to draw and interpret. A run chart may be used to study observed data for trends or patterns over a specified period of time and focus attention on vital changes in the process. The run chart is useful for tracking information and predicting trends or patterns. It can determine if a process has common cause or special cause variation.
random variation within a process. Rule Two - Trend. A trend on a run chart is five or more consecutive points all going up or all going down. If the value of two or.
A run chart plots your process data in the order that they were collected. Use a run chart to look for patterns or trends in your data that indicate the presence of special-cause variation. Patterns in your data indicate that the variation is due to special causes that should be investigated and corrected. A run chart is a line graph of data plotted over time.

Run Chart: Trends A Run Chart is a basic graph that displays data values in a time sequence (the order in which the data were generated). A Run Chart can be useful for identifying shifts and trends. Example: A supervisor of a customer service center collects data on the number of complaints that are filed each month. Run charts (often known as line graphs outside the quality management field) display process performance over time. Upward and downward trends, cycles, and large aberrations may be spotted and investigated further. In a run chart, events, shown on the y axis, are graphed against a time period on the x axis. Trends. A trend is five or more values all going in the same direction. Two consecutive points sharing the same value count as just one point in identifying trends. Runs. A run is a series of five points on one side of the median. These points can be going up, down, or a combination of up and down, as long as they remain on one side of the median line.

A run chart is a basic graph displays data as they evolve over time. Simple rules can be useful for identifying trends or shifts in process.
