Anything can be misleading, but in most cases a histogram conveys more information than a single number ever could.
Standard deviation and mean absolute deviation are both useful, but I think it's silly to suggest that we all adopt exactly one measure of variability to summarize data sets. When in doubt, make a fucking histogram.
