Q9 Changes Over Time

13. Dig the Data

The video above is posted on YouTube. It describes the importance of being counted, and urges everyone to be counted in the 2020 census, that already happened. The direct link below will take you to the U.S. Census Bureau site to play the video from their page.

Introduction

Students have access to lots of data that changes over time.  Understanding what this data tells us is important as it can help us make decisions about things like where we live, career choices, and the world around us.  In this Quest you will be learning about how data is collected about the state you live in as well as other states in the US; the increasing or decreasing populations in certain states; where most people live in the US; and how to interpret graphic representations of data that may inform things such as career choices.


I Can Statements

  • analyze data and interpret changes over time
  • use spreadsheets, charts and visual representations as tools to help organize and evaluate data
  • create, organize, analyze and share representations of data in a spreadsheet, chart, graph, and data plot formats with my teacher and classmates

Key Vocabulary

Census: The official count or survey of a population.

Findings: A conclusion reached after examination or investigation.

Inference: An idea or conclusion about something from known facts (evidence) and reasoning. An inference is also called an "educated guess."

Line graph: A graph that uses one or more lines to show changes in statistics over time or space.

Statistics: The collection and classification of data that are in the form of numbers. An example: Statistics are commonly used with sports, such as "runs batted in" (RBI) that help us predict things such as how likely a batter is to get a hit.

There are two options to complete this Quest.

  • The Standard Quest Steps located below
  • The Q9 Breakout: Changes Over Time that is located on a subpage on the menu to the right. There is a separate Student Checklist and Teacher Guide for the Breakout Challenge Activity on the subpage.

Please check with your teacher about which option to use.

Steps

1. What is a census? Learn about the Census Bureau and how it is a leading go-to source of statistical information, and how it was created to address the U.S. Constitution.

2. If you live in the U.S. visit the U.S. census statistics:

  • Our example will look at Michigan Facts, but if you live in a different state, select your own from the list
  • If you live in a different country, we encourage you to pick a U.S. state for this activity, and also locate the statistics for your country or area and search for data across different years that can show change.

3. Making inferences based on data is an important skill that is used in many different jobs.

  • Copy or download this 13.Q9 Changes Over Time Student Activity to explore the Census Data in more depth.
    • You will use this Student Activity document to answer challenge questions such as: the population change in Michigan, how people get to work, household computer use, and Video/Disc rental stores.
  • The image below is a screenshot of the Michigan population from the Census document as an example of answering questions using data.

Question: What changes do you observe about the median age of the population? How has it changed over the two time periods?
U.S. Census Bureau chart showing the Median Age change from 2010 (38.9 years) to 2019 (39.9)

  • Example observations: The Median age of the Michigan population increased from 38.9 years to 39.9 years from 2010 to 2019.
    The population of the state increased by approximately 100,000 people between 2010 and 2019.
 


Check with your teacher to see if you can work with a partner or small group on the next activities.

You will apply some spreadsheet skills to create line, bar, or other graphs to observe the change in the number of births in three different U.S. states over the same four year period.

Step-by-step Demonstration video

 

Play the Statistics in Schools Quiz to see if you can answer questions from the Census. The Quiz has questions such as: how many bedrooms are in an average U.S. house, how much candy an average American eats in one year, how do most people get to work, and more.

Population Bracketology Game (takes about 15 min):  Go to the following web site.

https://www.census.gov/dataviz/visualizations/057/

Compare the State Populations and see how well you do!

  • At the bottom of the bracket click on State Population
    • Click on New Game
      Screenshot of State Population circle selected, and above to select New Game.
  • Click on the State in each pairing that you think has the larger population
  • If you are correct the one you selected will show up in Green and you will get some points!
  • If you are incorrect it will show up in Red-orange like Oregon in the image below, but the correct state with a larger population, Colorado, will be shown on the bracket line. That way you can continue to gain points in the next round! 
    Screenshot showing a BYE and Kansas in green, with Kansas the winner of the pair, and Oregon and Colorado paired, with the wrong choice Oregon chosen in a red-orange, and Colorado advanced to the next round.
  • Some states will already be there in round one for you because they aren't in a pair and you will see the label "BYE" where only one state is in the pairing.
  • A perfect score is 63! See how close you can get.
  • You can start a new game, or if you want a different challenge play the game with Metro Area Population instead of State population.

Good luck!
