Design Evaluation: Statistical Tools for Assessing Your Design Quality

[@ahmedabdulrazzaq1159]

Hello sir... Thank you for your great video.

Thank you for the great video. What is the significance, if any, of the standard mean error in design evaluation?

[@StatisticsMadeEasybyStatEase]

I'm not sure exactly which statistic you are referring to, but any standard error is an estimate of variation for that statistic.

@@tafadzwankhoma1533 That is the calculated standard error after the experimenter inputs their "d" and "s". Continuing forward to 52:21, Martin is demonstrating changing these values, thus changing the signal/noise ratio. The blue horizontal line is the calculated value (the standard error). The values should be your desired precision, relative to the normal process variation. Refer to this video for more discussion: kzbin.info/www/bejne/q4qagKSDbsaqrqc
