So the interquartile range, we wanna figure out, well, what's sitting at the 25th percentile? And we wanna think about what's at the 75th percentile. And then we want to take the difference. That's what the interquartile range is. So let's do that. So first, the 25th percentile, we'd wanna look at the cumulative relative frequency. So 25th, this would be 30th, so 25th would be right around here.
