Given the essential role that data plays, many organizations will avoid any sort of data-related innovations or changes out of fear of creating problems. For an organization to run effectively and efficiently, it needs to have a reliable database. Data is key for handling daily activities and for making short and long-term decisions. Your database is a key part of your organization’s infrastructure, and if it goes down, it can create major problems. Automated Mainframe Intelligence (BMC AMI)ĭata is arguably the most important asset that your organization has.Control-M Application Workflow Orchestration.Accelerate With a Self-Managing Mainframe.Apply Artificial Intelligence to IT (AIOps).Thus, it measures what it claims to measure.Ī measurement can be highly reliable and yet not valid. The blood pressure cuff measures the construct as it is defined in the literature. The type of validity assessed in this example is that of construct validity. Situation induced - 'white coat syndrome' Non-random error affects the validity of the instrument.Īre there any non-random sources of error possible in your assessment of Ms. If the blood pressure cuff always reads high, then it affects all of the measurements. The closer to 1, the more reliable the measurement. It is expressed as a correlation coefficient ( r) which will range from 0 to 1. This is called the coefficient of stability. The type of reliability assessed in this example is retest reliability. What might you do to attempt to help establish reliability of Ms. List 3 things that might have introduced random error into Ms. The more random error, the less reliable the instrument. Random error consists of chance factors that affect the measurement. There are two types of errors that may affect your measurement, random and nonrandom. In order to determine if your measurements are reliable and valid, you must look for sources of error. How do I determine if my measurements are reliable and valid? Using an opthalmoscope to measure blood pressure would not be a valid method.

The use of a blood pressure cuff is considered to be valid because it is measuring blood pressure, not something else. Validity is the extent to which the construct measures what it says it is measuring.
