Classical test theory suggests that a "true score" esists for a given job and that true scores are stavle over time. Any measurement variation error are eliminated or aggragated across time or sources. Through this‚ researchers have commonly aggregated job analysis information in order the get the "true score" for every particular job‚ then the quality of job analysis datas are indexed with estimation of

In this experiment‚ I used one Nike soccer ball‚ one pair of Adidas soccer cleats‚ a soccer field‚ an air pump and a pressure gauge.
