On a newly developed IQ test, an individual scores at the 110 level on the first half of the test, and 150 on the second half of the test. What does this test appear to lack

Reliability

Step-by-step explanation:

The Reliability of a measurement or observation refers to its repeatability. If you measure or observe the same thing twice, how close are the two measurements or observations?

#The test results 110 1nd 150 are between 27% and 36% depending on which direction you take. That variation is wide apart and the test can't be considered reliable.
