What is the coefficient of variation?
Cv = SD x 100 / mean

Serum
What is a graph consisting of rectangles whose area is proportional to the frequency of a variable and whose width is equal to frequency of variable?
Histogram
What is a z-score?
Expressing an observation in terms of how many standard deviations it is from the mean.
Z-score = observation - mean / standard deviation
