I'm trying to understand statistics and specifically, I want to know the numerical value or representation of 1 sigma. Could someone please explain what 1 sigma means in numerical terms?
When we move to 2 sigma, this percentage increases to 95.4%, meaning that 95.4% of the data lies within two standard deviations from the mean.

For instance, 1 sigma translates to 32% of the time where measurements do not fall within the range of 45 +/- 10 km/s.

At 3 sigma, the percentage rises to 99.7%, suggesting that almost all data points, 99.7% to be precise, are within three standard deviations of the mean.

For 4 sigma and above, the percentage approaches NEAR perfection, with 99.99% of the data falling within four standard deviations from the mean.

The concept of sigma is widely used in statistics to represent the level of deviation from a mean value.
