QM Registry Ch.2
QM Tools and Procedures
| Question | Answer |
|---|---|
| The extent to which a measurement is close to the true value. AKA validity | accuracy |
| Philosophy of keeping radiation exposure to a minimum | as low as reasonably achievable |
| A causal analysis tool. AKA fishbone chart or Ishikawa diagram | cause-and-effect diagram |
| The central position of a sample frequency | central tendency |
| Variables that have an infinite range of mathematic values | continuous variables |
| A modification of the trend chart in which statistically determined upper and lower control limits are placed | control chart |
| The information or measurements that were acquired by evaluating the particular sample | data set |
| Those variables that are observed in statistical studies to change in response to independent variables and are not controlled during the study | dependent variable |
| Variables that have only two values or choices | dichotomous variables |
| Measurement that incorporates the total dosage of radiation along with the area of field that is being used | dose area product |
| A pictorial representation of the individual steps required in a process | flowchart |
| The number of repetitions of any phenomenon within a fixed period | frequency |
| Creates a bell-shaped curve that is continuous with both tails extending to infinity. AKA normal distribution | Gaussian distribution |
| A data display tool in the form of a bar graph that plots the most frequent occurrence of a quantity in the center | histogram |
| Any occurrence that is not consistent with the routine care of a patient or the normal course of events at a particular facility | incident |
| Those that are deliberately manipulated to invoke a change on the dependent variables | independent variable |
| Any activity that costs a facility either money or its reputation | loss potential |
| The average set of observations | mean |
| A point on a scale of measurement above which are exactly one half of the values and below which are the other half of the values | median |
| The one value that occurs with the most frequency | mode |
| A causal analysis tool that is a variation of a histogram | Pareto chart |
| Random distribution in which the variance is equal to the mean | Poisson distribution |
| Any group measured for some variable characteristic from which samples may be taken for statistical purposes | population |
| Refers to an individual's state of mind that would create a desire for a particular outcome | prejudice |
| Refers to the difference between the highest and lowest values and is a measure of the dispersion of the data distribution | range |
| The accuracy, dependability, or validity of the data that has been collected. AKA precision | reliability |
| The ability to identify potential risks to patients, employees, and visitors to the healthcare institution and institute processes that minimize these risks | risk management |
| The number of items that are actually measured from a population | sample |
| A graph that demonstrates a possible correlation between two variables | scatter plot |
| The amount of variance in a sample | standard deviation |
| A graph that pictorially demonstrates whether key indicators are moving up or down over a given period. AKA run chart | trend chart |
| Evaluation of data collected over a period of time for the purpose of identifying patterns or changes | trending |
| A numeric representation of the dispersion of data around the mean in a given sample | variance |
| Refers to anything that would cause a process to deviate from acceptable standards | variation |
