    Quantile versus Percentage of cases

    942268
      I was wondering why in the one picture I'm getting at a quantile of 30% the records cumulative is 30% however, in the other picture at a quantile of 25% the records cumulative is 30% why are they different numbers? since there are 100 quantiles arn't they just the percent of cases except organized from those with the highest probability of being the target value to the lowest probability of being the target value?

      Here are the links too the two photos
