1. Explain the sudden dip on the following graph. The graph shows Overseas arrivals to the United States. This means that the dip is showing a drop in the amount of people coming to the United States from other countries in 2001. This happened because in 2001, the terrorist attack on the twin towers happened, so less people traveled during this time period. In 2002, the amount picked up a little bit, but still not the same number of people in 2000. The graph continually rose until 2001, when 9/11 happened.
2. Explain how statistics can help to elucidate/explain the significance of historical events. Statistics can help explain the significance historical events because like the graph to the first question, it can show the effect compared to other times. For example, on Gap Minder when using the dots on different counties, the dots will suddenly get smaller or bigger depending on if something happened there. In class we looked at a graph in Gap Minder that showed the effects of earthquakes and in Indonesia in 2004 the dot got a lot bigger because there was a huge tsunami there and it had a great effect on the country.
