GRADUATED TABLES-THIRD SERIES. The following Table exhibits the ratio of the mean average attendance in each town to the whole number of children between 5 and 15, according to the returns. The mean average is found by adding the average attendance in Summer to the average attendance in Winter, and dividing the amount by 2. In some cases, the true mean average is not obtained by this process, for reasons peculiar to the schools of some towns. In such cases school committees were requested to indicate in their returns the true mean average, that their result may be inserted in the Table. The ratio is expressed in decimals, continued to four figures, the first two of which are separated from the last two by a point, as only the two former are essential to denote the real per cent. Yet the ratios of many towns are so nearly equal, or the difference is so small a fraction, that the first two decimals, with the appropriate mathematical sign appended, indicate no distinction. The continuation of the decimals, therefore, is simply to indicate a priority in cases, where without such continuation, the ratios would appear to be precisely similar. In several cases the ratio of attendance exhibited in the Table is more than 100 per cent. This result, supposing the registers to have been properly kept, and the returns correctly made, is to be thus explained:-the mean average attendance upon all the Public Schools, being compared with the whole number of children in the town between 5 and 15, the result may be over 100 per cent., because the attendance of children under 5 and over 15, may more than compensate for the absence of children between those ages. Teachers and committees are sometimes not sufficiently careful to secure an accurate ret rn of the average attendance. On this account it is not claimed that the towns in all cases, are entitled to the exact precedence given them in the Table. They may not be thus entitled by the actual attendance, while they are so according to the returns. GRADUATED TABLES-THIRD SERIES.
