Homework Lesson 1: Box and Whisker Plots
Data on the number of hours per week of television viewing was collected on a sample of Americans. The graphs below summarize this data for two age groups.
1. What is the median number of hours of television viewing per week for each age group?
12-17 age group median ________ 18-24 age group median________
2. What is the interquartile range for each age group?
12-17 age group interquartile range_____ 18-24 age group interquartile range _____
3. Describe the difference between the medians as a multiple of the interquartile range.
Data on the number of hours per week of television viewing was collected on a sample of Americans. The
graphs below summarize this data for two age groups.
4. What is the median number of hours of television viewing per week for each age group?
12-17 age group median ________ 50-64 age group median________
5. What is the interquartile range for each age group?
12-17 age group interquartile range_____ 50-64 age group interquartile range _____
6. Describe the difference between the medians as a multiple of the interquartile range.
In a local park, Jeremy collected data on the heights of two types of trees by measuring the heights of randomly selected trees of these types: Tree Type “A” and Tree Type “B”. He displayed each distribution of sample
heights in the following box plots:
7. Compare the two distributions. What inferences can you draw about the heights of the two types of trees?
Homework Lesson 2: MAD
Peter is comparing the lengths of words in a seventh grade geometry book to the lengths of words in a tenth grade geometry book for a statistics project. He plotted the length of 300 randomly selected words from each
book and calculated the mean and the mean absolute deviation (MAD) for each set of data.
Mean = 4.0 Mean = 6.5 MAD = 1.4 MAD = 2.5
Use the mean and the MAD to compare the two distributions. What inferences can you draw about the lengths
of words in the two textbooks? MOVIES The table shows the running time in minutes for two kinds of movies. Find the mean absolute deviation for each set of data. Round to the nearest hundredth. Then write a few sentences comparing their variation.
WATER PARKS The table shows the height of waterslides at two different water parks. Find the mean absolute deviation for each set of data. Round to the nearest hundredth Then write a few sentences comparing their variation.
Homework Lesson 3: Population Characteristics vs Sample Statistics
6. Read the following and underline 3 interesting points.
7. Go to http://www.census.gov/2010census/popmap/ipmtext.php?fl=12 and play around on the site to see the different characteristics of Florida. Click on 2010 Census Home or the interactive population map in the top right corner to investigate further.
