What is the percentage agreement (accuracy)?
Homework Answers
Percentage agreement = Number of times in which both test and retest gave same result / Total number of results
= (80+3)/(80+9+8+3)
= 83/100
= 0.83
= 83%

The test-retest method is one way of establishing the reliability of a test. The test is administered, and then, at a later date, the same test is re-administered to the same individuals. The correlation coefficient is computed between the two sets of scores. The following test scores were obtained in a test-retest situation. (Give your answers correct to two decimal places.) First Score 86 85 97 65 77 66 67 80 90 93 Second Score 79 73 60 62 80...

A study was conducted to compare the proportion of drivers in Boston and New York who wore seat belts while driving. Data were collected, and the proportion wearing seat belts in Boston was 0.581 and the proportion wearing seat belts in New York was 0.832. Due to local laws at the time the study was conducted, it was suspected that a smaller proportion of drivers wear seat belts in Boston than New York. (a) Find the test statistic for this...
