The document contains a 10 question quiz about measures of central tendency including the mean, median, and mode. Questions 1-3 ask about which measure is most affected by extreme values and the levels of measurement required for the median and mode. Questions 4-5 provide examples to calculate the median and mean. Questions 6-7 ask about the best measure of central tendency and situations where harmonic mean and geometric mean are not applicable. Questions 8-9 give examples to calculate the mean of series. Question 10 asks to explain the concept of geometric mean with an example.
