答案
解析 [参考答案]效度:是指测量的正确性,即一个测验能够测量出其所要测量的东西的程度。效度的重要性大于信度,因为一个低效度的测验,即使具有很好的信度,也不能获得有用的资料。

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
