Used with almost any process and with any type of data: measurements, counts, percentages, ratios, etc. but don’t provide the same depth of analysis as a control chart.
This type of cotrol chart is used for variable (continuous) data (e.g. time, money, height/weight, temperature, etc.) or to record measures for each observed unit.
Used to display counts of things we are trying to avoid happening, (e.g. number of violence incidents, number of falls, etc.) where a fixed sample size exists.
An attributes control chart used to display counts for an inconsistent sample size or "area of opportunity", where the number of patients on the wards varies considerably.
It displays proportions or percentages for an equal or unequal sample size and is used when the data is based on two classifications (e.g. Yes/No, Pass/Fail, etc.)
Used when the error or undesired incident occurs infrequently in a particular setting (e.g. incidents of physical violence on wards, or incidents of falls).
Geometric Chart is used when the error or undesired incident occurs infrequently in a particular setting (e.g. medication error, or incidents of MRSA on a ward).
Used to chart data that is measured and comprised of multiple sub-groups and you have breakdowns of this data, useful when the sample size is relatively large and variable.
