The variation in the number of galaxies is a measure of the lumpiness of the galaxy distribution on a scale, in this case, of 40 million light-years. 由于星系有聚集現象，每個(gè)球所包含的星系數量會(huì )有所變異，這個(gè)變異量就代表星系分布起伏在該尺度的強度。
In the second study, the results of testing the measurement model of the Health Behavior Scale indicated good reliability and accounted for a large amount of variance. 第二個(gè)研究是做健康行為量表整個(gè)量測模式的檢定，結果顯示本量表具有良好的信度，且能解釋大的變異量。
