The term reliability in psychological research refers to the consistency of a research study or measuring test. For example, if a person weighs themselves during the course of a day they would expect to see a similar reading. Scales which measured weight differently each time would be of little use.

You measure the width of a doorway and find that it is 1.20 m wide. Find the greatest possible error of your measurement
elena-s [515]
Given that the distance between two lines in the measurement instrument is 0.01m, the maximum error should be 0.01m/2 = 0.005 m.

If you do a good work, the real measure is 1.20m +/- 0.005m, this is between 1.195 and 1.205.
