  1. Day 5 • 2nd day on previous material • Also, we need to address when finding the mean is the best strategy, when finding the median is best, and when finding the mode is best.

  2. This measure is most useful when: • Mean – the data have no outliers (values much larger or smaller than the rest of the data) • Median – the data contains outliers • Mode – data have many repeated numbers or the data is categorical in nature

  3. Which is the best measure of center for this data set?

  4. Which is the best measure of center for this data set?

  5. Which is the best measure of center for this data set?

  6. 1. Jamal said that the number that best represented the following set of data is 27. Which measure of central tendency is he referring to? 28, 32, 21, 25, 33, 32, 20, 26 • 2. The number of books read by the students in each core literacy class is: 104, 90, 162, 134, 110, 97, 145, 126. Which measure of central tendency best describes the data? Explain.

  7. 3. The high temperatures for one week are 79°, 81°, 77°, 81°, 82°, 75°, and 76°. If the temperature on the eighth day is 80°, which of the following would be true? A. The mode will change B. The mean will increase and the median will remain the same C. The median will increase and the mean will remain the same D. Both the mean and the median will increase Glencoe Pre-Algebra (2012) pg. 779
