1. Test-retest
In the test-retest method of determining reliability, the same instrument is administered twice to the same population, and if the results are the same, stability of measurement is assumed.
An example would be giving the same survey questions to a group of people, then latter giving the same group of people the same survey with the same question. Now if both surveys have the same results then there is reliability in the survey.
2. Multiple forms
Multiple forms involve the administration of alternate forms of the instrument to the same group.
What else can I help you with?
What are statistical levels of measurement?
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.
What is the three things that each axis of a graph is labeled with?
Each axis is labeled with the name of the variable, the unit of measurement, and a range of values.
What is the probability of rolling doubles greater than three?
In the case of dice, greater than three, means 4,5 or 6. So, obviously, three cases out of 36.
What assumptions is not made for the F test for comparing three or more means?
The sample size must be equal
What step in risk management process is focused on determining the probability and severity of a hazard occurring?
Assess hazards is the step in the composite risk management process that is focused on determining the probability and severity of a hazard occurring.
What is number of digits in a measurement that you know with a certain degree of reliability?
The number of digits in a measurement that you know with a certain degree of reliability is referred to as significant figures. Significant figures include all the known digits in a measurement plus one estimated digit, indicating the precision of the measurement. For example, if a measurement is recorded as 12.3, it has three significant figures, reflecting a reliable accuracy up to the tenths place. The more significant figures, the greater the confidence in the accuracy of the measurement.
What three tools can be started from the reliability and performance monitor?
Resource View, Performance Monitor, and Reliability Monitor
What is three and three quarter?
A measurement
What are three characteristics of network reliability?
Redundant hardware provides enhanced reliability. Fault tolerance is a measure of reliability. The longer the MTBF, the greater the reliability.
What are three synonyms for credibility?
trustworthiness, reliability, and integrity
How do you add three different measurement of centimeters?
I assume the example below is what the question means? 45cm + 12.5cm + 4.75cm = 62.25 cm
What are three influences on the reliability of a system?
Hardware software operator
Which three windows 7 tools are contained in the vista reliability and performance monitor?
Resource View, Performance Monitor, and Reliability Monitor.
What is the measurement for three fourths?
.75
What are the three-stage procedures of work measurement systems?
All work measurement systems are based on the same, simple three-stage procedure: analysis, data collection and measurement, and synthesis.
What is the measurement of the significant figure of 0.00121?
Three
What are levels of measurement?
Three basic levels of measurement are nominal, ordinal, and interval/interval-ratio.
