What should be the value of the standard deviation? like what's a good standard deviation?

for an approximate answer, estimate your coefficient of variation (cv=standard deviation / mean).as a rule of thumb, a cv > = 1 indicates a relatively high variation, while a cv < 1 can be considered low. this means that distributions with a coefficient of variation higher than 1 are considered to be high variance whereas those with a cv lower than 1 are considered to be low-variance.

remember,   standard deviations aren't "good" or "bad". they are indicators of how spread out your data is. a "good" sd depends if you expect your distribution to be centered or spread out around the mean. this really depends on your data.

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
