SD means self destruct
The standard error (SE) is calculated by dividing the standard deviation (SD) of a sample by the square root of the sample size (n). The formula is SE = SD / √n. This provides an estimate of how much the sample mean is likely to vary from the true population mean. A smaller SE indicates that the sample mean is a more accurate reflection of the population mean.

Variance. Although usually it is the SD that is calculated from the variance.
The empirical rule is 68 - 95 - 99.7. 68% is the area for +/- 1 standard deviation (SD) from the mean, 95% is the area for +/- 2 SD from the mean; and 99.7% is the area for +/- 3 SD from the mean.
I assume you mean CARD instead of port; an SD port and an SD slot are essentially the same thing. The answer is that you don't. You can, of course, get an SD card reader that plugs into a USB port.

The numbers must be greater than (mean - 2*sd) and laess than (mean + 2*sd).
