Answer (2)
Voter turnout in states with Election-Day Registration (EDR) was higher than in states without EDR in both 2008 and 2012.
In 2008, the difference in voter turnout was 72% − 62% = 10% .
In 2012, the difference in voter turnout was 65% − 58% = 7% .
Therefore, election-day registration helped to increase voter turnout. It helped to increase voter turnout.
Explanation
Analyze the problem and data We are given a table that compares voter turnout in states with and without Election-Day Registration (EDR) for the years 2008 and 2012. Our goal is to determine what conclusion can be drawn about election-day registration in states where it was an option, based on the provided data.
Examine voter turnout percentages Let's examine the voter turnout percentages for each category:
States with EDR:
2008: 72%
2012: 65%
States without EDR:
2008: 62%
2012: 58%
Compare voter turnout with and without EDR Now, let's compare the voter turnout in states with EDR to those without EDR for each year:
In 2008, states with EDR had a 72% turnout, while states without EDR had a 62% turnout. The difference is 72% − 62% = 10% .
In 2012, states with EDR had a 65% turnout, while states without EDR had a 58% turnout. The difference is 65% − 58% = 7% .
Draw a conclusion In both 2008 and 2012, the voter turnout was higher in states that offered Election-Day Registration compared to states that did not. This suggests that EDR may have contributed to increased voter turnout.
Final Answer Based on the data, we can conclude that election-day registration helped to increase voter turnout.
Examples
Understanding the impact of policies like Election-Day Registration (EDR) is crucial for shaping effective strategies to boost civic engagement. For example, if a city council is debating whether to implement EDR, they can analyze data from other states to predict potential increases in voter turnout. If a state observes a 10% increase in voter turnout after implementing EDR, this information can be used to advocate for similar policies in other regions, enhancing democratic participation.
The total charge delivered by the device is 450 C, and using the charge of a single electron, approximately 2.81 x 10^21 electrons flow through the device in 30 seconds.
