No.
standard deviation = √variance
Standard deviation must decrease while variance simultaneously decreases, and standard deviation must increase while variance simultaneously increases.
standard deviation = √variance
Standard deviation must decrease while variance simultaneously decreases, and standard deviation must increase while variance simultaneously increases.

Standard deviation is the square root of variance. If the variance decreases, the standard deviation must decrease.
