I have a dataset that is highly skewed right. When calculating Z-score, I was expecting to see values up to as high as 6 (6 standard deviations from the mean). In my head, I was thinking that 6 was the highest possible value. I'm pretty certain my calculation is correct, but would just like a "nod" that it is technically possible to have a Z score of 21.4, or a "shake" that no, that's not possible.

The mean is 11452.7 and stdev is 53563.65.

Thank you!
