Control charts use historical data to evaluate whether current data indicate process variation is in control (consistent) or out of control (unpredictable). This is a key concept in public health/epidemiology. We now recognize that an understanding of mathematical methods and the use of statistics to assess data in epidemiology and public health are critical for identifying the causes of disease, modes of transmission, appropriate control and prevention measures, and for prioritizing and evaluating activities. is the sum of a set of numbers divided by the count of how many numbers there are. Causation develops the relationship idea further by asserting the directionality, i.e. Medicare beneficiaries renew their health plans at end of each year so you could see lower volume of treatment at the beginning of each year when plan deductibles reset . Even it can make able to reach a leading position if reliable solutions are found. A correlation of 1 means perfect positive correlation, -1 means perfect negative correlation, while 0 means no relationship at all. E.g.
