You can put this solution on YOUR website! Numbers are in order Median is the middle number or 6.
 The lower half consists of 3 and 5; the first quartile is the middle of it, or 4.
 The third quartile is therefore 89.
 Std. deviation requires mean first, which is sum/5 or 6
 squared deviations from mean, added, are 4+1+0+1+4 or 10
 divide by n-1 or 4 observations, and that is 2.5
 Take the square root, which is 1.58
