表三和表四为短时记忆广度各项实验数据关于性别的独立样本检验。由上表可知，由于3个数和5个数两组的标准差为0，所以它们的t值无法计算。短时记忆广度在男女性别上没有显著性差异，当出现的数字为4个数和9个数的时候，男女的正确率有显著性差异。

表五是短时记忆广度的各项数据与时间知觉、简单反应时、工作效率和注意广度值的相关。由上表可知，短时记忆广度值与7~12个数的正确率显著相关，与时间知觉相对误差、简单反应时、工作效率及注意广度值均没有显著性相关。其中，6个数的正确率与8个数的正确率显著相关，9个数的正确率与10个数的正确率显著相关，10个数的正确率与11个数、12个数的正确率都显著相关。由此可得出，各个记忆模块的正确率之间也有一定的关系。短时记忆广度的各项数据与时间知觉相对误差、简单反应时、工作效率、注意广度值均没有显著性相关。
