The standard deviation ($s_x = 21.70$) measures the typical amount by which data points deviate from the mean ($\bar{x}=34.70$). It does not mean the data always varies by that amount, nor does it directly give the range of fluctuation. It indicates the variability in the data.

The amount of money spent by these 50 shoppers typically varied by about $21.70 from the mean of $34.70.
