Create a chart to help interpret important findings.

For your final chart, interpret the findings from the chart in text. Full sentences required.

  1. Most credits are requested between the amounts of 0 to 5,000.

  2. Males almost double the amount of credit requests compared to female.

  3. Most of the loans last between 0 to 20 months to be payed back.  

  4. There are a few outliers, which could be influenced by the age of the person and the purpose to why requesting the credit. Usually young people are predominant in requesting credits because they are the ones who are starting to settle down, while elderly already have a retired found.  

  5. There seems to be a correlation between the credit amount requested and the duration to payback. The shorter the amount the fastest the payment happens, and vice versa.
