A major difficulty for children with this diagnosis of dyslexia surrounds the skills of reading. A special education teacher is interested in knowing whether a new reading technique increases reading skills for children diagnosed with dyslexia. She uses the WRAT as a way of measuring reading skills and the average for this test is 55. She takes a random sample of 25 children diagnosed with dyslexia, employs her reading program with them and finds their mean on the WRAT to be 56.1 with an estimated standard deviation of 4.8.
