Similarly, we should see variation in the number of child casualties that tracks the variation in the number of women. This is because the daily variation in death counts is caused by the variation in the number of strikes on residential buildings and tunnels which should result in considerable variability in the totals but less variation in the percentage of deaths across groups. This is a basic statistical fact about chance variability. Consequently, on the days with many women casualties there should be large numbers of children casualties, and on the days when just a few women are reported to have been killed, just a few children should be reported. This relationship can be measured and quantified by the R-square (R2 ) statistic that measures how correlated the daily casualty count for women is with the daily casualty count for children. If the numbers were real, we would expect R2 to be substantively larger than 0, tending closer to 1.0. But R2 is .017 which is statistically and substantively not different from 0.
