Step-by-step explanation:

Dylan took the Whaddayanno IQ Test today, and his IQ score was 130. Last week, his IQ score on the same test was 70. The Whaddayanno IQ Test appears to lack reliability.

Reliability can be defined as the extent to which an  experiment or test provides the same result on  repeated trials.
