对微小的周期性变化的研究之所以困难，主要是因为常常存在这样的疑问，即用普通方法得到的结果是偶然的，还是证明了某些真正的周期性作用的原因。只要注意为追踪太阳黑子在地球现象（如降雨或温度）中的周期而进行的许多计算，就可以表明，根据偶然性因素的大小，从同一证据中可以得出完全不同的结论。
THE investigation of small periodical changes is rendered difficult chiefly by the doubt which so often exists, whether the results obtained by the ordinary methods are due to accident, or prove some real periodically acting cause. Attention need only be drawn to the many calculations which have been made to trace the sunspot period in terrestrial phenomena, such as rainfall or temperature, to show that widely different conclusions may be drawn from the same evidence according as greater or smaller value is attached to the element of chance.
