Option 3:

Retreat the line and build a new capital city. The government is considering whether to defend Jakarta’s coastline at all. If the coastline is not defended it is called “retreat the line”. To relieve some of the pressures on Jakarta, the government is planning on moving to a brand-new city in another part of Indonesia with no risk of flooding.

Study Figure 6. Describe the location of the proposed new capital city in relation to Jakarta.

Tick (√) two advantages of using the mean to analyse this data.

  • It takes the middle value of the data.

  • It can be affected by outliers

  • The range of the data set is small.

  • It allows comparison of the data between time periods.

  • It shows a clear difference between the highest and lowest values.
