1. What is the BEST measure of the central tendency for the following set of numbers: 18, 34, 56, 67, 875 a. Mean b. Median c. Mode d. Standard Deviation e. None of above 2. Which of the following is/are measure(s) of variability? (select all that apply) a. mean b. range c. mode d. variance e. linear transformation 3. For a set of numbers, if the mean is equal to the median, its distribution might be: a. Right-skewed b. Left-skewed c. Normally distributed d. Positively-skewed 4. In the graph, there are two distrubitions and we can tell (check all that apply): a. The mean of distribution A> the mean of distribution B b. The mean of distribution A < the mean of distribution B c. The standard deviation of distribution A> the std deviation of distribution B d. The standard deviation of distribution A= the st deviation of distribution B   5. Which of the following can measure variability? (Select all that apply) a. mean b. median c. range d. variance e. standard deviation f. Interquartile range 6. A researcher collected BMI (Body Mass Index) of 50 students in an Engineering school. He found the mean BMI was much smaller than the median BMI. The reason for this might be: a. Several students had much smaller BMI scores than the other students b. Several students had much larger BMI scores than the rest c. The researcher made some measurement errors d. All the...
