To see how to calculate the SD, watch this video: ruclips.net/video/A-c8CKwHZ1A/видео.html If you square the differences between the values and the mean (-0.5), you should get: 6.25 2.25 6.25 2.25 0.25 0.25 If you then sum these values and divide by 5, you should get: 3.5 If you then take the square root of 3.5, you should get about: 1.87
this is actually a really undervalued channel!! I have been looking your videos for hours, cause I am having an exam, you explain everything very simply and effectively. nice jobb
