The binomial test table is split by the values of Churn within last month. The first test selects only those customers in the sample who did not churn last month.

Within this first split file group, the cut point has created two groups. The first group consists of those customers who did not churn and whose household income is less than or equal to the median for the total sample.

  • In these data, just about half of those who did not churn fall at or below median income. As we would expect, the difference in proportions is not significant.
  • However, of those 274 customers who churned last month, the proportion with household incomes at or below the median is significantly different from the null hypothesis value. Those who churn tend to be the less affluent customers.
