(a) Find the mean, median, mode, sample variance, and range.
{54, 62, 54, 57, 60, 61, 53, 63, 59, 56}

(1) Compute the mean - this is the average height:
mean = sum(heights) / n where n is the sample size, in this case, n = 10.

mean = (54 + 62 + 54 + 57 + 60 + 61 + 53 + 63 + 59 + 56)/10 = 57.9

(2) Compute the median - this is the value of the middle observation when ranked, or in this case, the average of the 2 middle observations ...
