Which of the following statements about the histogram are true? Select all that apply.
Sets A and B differ only by one value. What do you notice about mean, median, and mode for both sets? Which one is more representative of the average (age) in this context (hint: one of the values is more "swayed" by any outliers (or values that are much higher or lower than the rest))? Note that set C consists of values in set A plus 5. What do you notice about the mean, median, and mode for both sets? What about variance and standard deviation? Explain.
