  4. Competency 7 Practice 1c. What is the median age of the 7 children whose ages are: 11,  10,  13,  11,  12,  16,  14

  6. Competency 7 Practice 2a. Which measure of central tendency should be used? SEA College would like to prove that students with a college degree make more money on average than people with no degree. According to their data, the salaries are: $50,000, $50,000, $55,000, $45, 000, $49,000 and $200,000. Would it be best for the SEA to tell students the mean or median of the data if they want to show a high average of pay.

  7. Competency 7 Practice 2b. Which measure of central tendency should be used? Tom is graduating from SEA College and would like a realistic estimate of the amount of money most new graduates earn. According to the data at SEA, the starting salaries of the last five graduates were: $50,000, $50,000, $55,000, $45, 000, $49,000 and $200,000. Would it be best for Tom calculate the mean or the median to find the most realistic view of starting salaries?

  8. Competency 7 Practice 2c. Which measure of central tendency should be used? Brianna is arguing with her brother, T.J., about who is on the better soccer team. She’s using the data from their last five games. The table below shows their scores. Brianna says her team is better because they have the highest average of points. Is this correct? What measure of central tendency could T.J. use to prove her wrong?

The times in hours were: 1, 1.25, 1, 1.5, 1, 3.5, 1.25, 1.5, 1, 1, 1, 1.5, 1, 1.25, 1.75, 1.25,1. If Mr. Brown wants a clear view of how long the average student takes to complete homework, should he calculate the mean or median? Could the mode be used? Explain.
