Project Chapter 3



⦁ For the following data:

Variable: Number of books read by subject per year
X: 12, 8, 6, 7, 25, 23, 11, 12, 13, 10, 11, 7, 8, 7, 8, 11, 8, 9, 9.

⦁ Find the Mean, Median and Mode for the data above.

⦁ What is the shape of your distribution?





⦁ Do any of the data points look like possible outliers? Explain your answer.






⦁ Write one characteristic of the mean that does NOT apply to the other measures of central tendency.








⦁ Write one characteristic of the median that does NOT apply to the other measures of central tendency.








⦁ Write one characteristic of the mode that does NOT apply to the other measures of central tendency.

⦁ Find the Mean, Median and Mode.

⦁ What is the shape of the distribution?

⦁ REMOVE the subjects X = 10 and calculate the Mean, the Median and the Mode.


⦁ Explain the differences (changes between measures of central tendency, changes in the shape of the distribution) between your answers for a and c.







⦁ Calculate all possible measures of central tendency from the frequency table below. Explain your answer.
