Included in the data based on results of scores taken from tests scored at Educational Records Bureau for its independent school members in the fall 1971, spring 1972, fall 1972, and spring 1973 testing programs, are tables which present the distribution of class medians with corresponding percentile ranks at each score interval. The "F", or frequency column, in each table reveals the number of classes having a median score falling at each particular interval on the score scale. Additional information in in this group of tables includes the number of class medians available for the distribution, the first and third quartile scores, and the range of median scores included in the distribution, showing the highest and the lowest scores. A second group of tables contains summary statistics for all individual pupil scores included in the program. The information contained in this summary includes the range of individual scores, low to high, the scores falling at the first quartile, median, and third quartile, and the number of pupils' scores included in the data. The tables included here are useful when studying year to year test results. (Author/RC)
