Induction to Topic and Motivation

  • Data collected from divorce records filed in Xalapa, Mexico between 2000-2015.

  • Our analyses focus on observing any trends between the characteristics of the two people getting the divorce and the frequency of divorces.

  • We focused on the education level, income, and age gap of those getting the divorce.

Interpretation and Evaluation of Significance

Education Analysis:The calculated p-value was 0, meaning we reject the null hypothesis. Therefore, there is a significant difference in the education level between divorcees with a mean difference of around 0.48156.

Age Gap Analysis: The calculated p-value was 1, meaning we fail to reject the null hypothesis. There is no significant evidence that the true mean age gap of divorcees is greater than 5.

Income Analysis: After dropping the outliers we obtain a p-value of 0.12 so we fail to reject the null hypothesis. There is no significant evidence that the true mean difference in income between the individuals being divorced is not 0.

Conclusions + future work

  • Of the factors analyzed (education, income, and age differences), only education differences seemed to play a significant role in divorces

  • The interpretations could be wrong due to us not being able to compare divorce rates to total marriage rates

  • Future works could include finding marriage rates and analyzing those alongside divorce rates

  • And we could examine data from different parts of Mexico, or nationally.
