Population Challenge 1:

Find data on the number of males and females in the United States, as well as the ethnicity of the population of the United States in 2000. Print out Worksheet 1 and record your findings.

1. Using your knowledge of the various types of graphs, create an appropriate graph for each set of data.
   
   
2. Explain your choice of graph type in at least two sentences for each set of data.

Worksheet 1

Name:_____________________________________

Date:_________________

Fill in each chart with the appropriate information.

Ethnicity and U.S. Population in 2000

Ethnicity and Gender in 2000

Population Challenge 2:

1. Find and record the population of each state in the United States using Worksheet 2.
   
   
2. Use your findings to estimate the total population of the United States. Record your estimate on Worksheet 2.
   
   
3. Find the actual population of the United States and compare this number with your estimate. Record the difference between your estimate and the actual population on Worksheet 2.
   
   
4. Find the mean, median, and mode of the state population data. Determine which measure best describes the central tendency of the data and explain your reasoning. Record your answers on Worksheet 2.
   
   
5. Research the change in the U.S. population since 1950. Then create a graph that represents this data. Use your graph to predict the population of the United States in 2015. Explain how you arrived at your prediction in 2-4 sentences.

Worksheet 2

Name:_____________________________________

Date:_________________

1. Fill in the chart with the appropriate information.

2. Estimate the total population of the United States using the above data.
   
   
3. Research to find the actual population of the U.S. What is the difference between your estimate and the actual population?
   
   
4. Find the mean, median, and mode of the state population data. Which measure best describes the central tendency of the data? Explain your reasoning.
   
   
5. Now that you have researched the history of the population of the U.S., create your graph below or on graph paper. What is your prediction for 2015? Explain your prediction in 2-4 sentences.

Population Challenge 3:

Create a presentation that includes the following:

• Worksheet 1 and both of your graphs on gender and ethnicity in the United States; and
  
• Worksheet 2 and your graph of the U.S. population since 1950.

Choose one state, research its gender and ethnic make-up in the year 2000. Create two graphs similar to those done in Population Challenge 1 and write a few sentences comparing the gender and ethnic make-up of that state to the gender and ethnic make-up of the United States as a whole.

Population Challenge 1:

1. Remember to label and title your graphs.
   
   
2. The following are the different types of graphs you can choose from: frequency tables, bar graphs, line graphs, and stem-and-leaf plots. Your text has descriptions of each type of graph.
   
   
3. Since the numbers you are graphing are large, rounding the numbers to the nearest thousand or hundred thousand might be helpful.
   
   
4. Remember, your second graph has three components: ethnicity, female, and male. All three need to be on the same graph.
   

Population Challenge 2:

1. Remember to label and title your graphs.
   
   
2. Since the numbers you are graphing are large, rounding the numbers to the nearest thousand or hundred thousand might be helpful.
   
   
3. To review calculating the mean, median, and mode of a set of data, refer to Lessons 2-6 and 2-7 in your text.

Some of the presentations that you could create are:

• a booklet,
  
• a poster, or
  
• a newspaper/magazine article.
