The weighted mean - how it works

[@krumpy8259]

Beautiful video, beautiful channel. Love you.

[@XtremeTerror100]

An easy and phenomenal explanation. Good work. Keep it up!

Nice

[@AbbasAtashdehghan]

Thank you once more for the vidoes. Is it possible to include a video regarding LSMean and how it differs from the arithmetic mean? When should we think about LSMean? ....

[@brazilfootball]

Is this at all related to a moving average (from time series analysis)?

[@tilestats]

No, but you can have a weigthed moving average, where, for example, more recent time points get a greater weight.

@@tilestats Oh ok, thank you! Also, I'd be very much interested to see a video on moving averages too! Too many videos on it are about financing/stocks...

Does weighted mean difference have standard deviation?

[@tilestats]

Yes, you can also calculate weighted SD.

[@mesiazul8435]

@@tilestats is it possible to calculate the weighted SD from only the values as shown: Participants in the ezetimibe and statins group had lower LDL-C (mean difference -13.14 mg/dL; 95% CI -16.83 to -9.44; p= 0.00001)?

@@tilestats Do you know how should I calculate the weighted SD?
