I think the range is just max - min, right?

Wait, are we sure about those images? They look off.

Totally agree, those positions are key for IQR!

First quartile is at 25%, third quartile at 75%.

I think the range is just the maximum minus the minimum, but I need to double-check how to find those values from the quartiles given.

I feel like I might confuse the positions of the quartiles. Is it Q1 at n/4 and Q3 at 3n/4? I hope I remember that correctly!

I remember we talked about calculating the range and interquartile range in class, but I'm a bit unsure about how to apply it to this specific dataset.

This question seems similar to one we practiced last week. I think we just need to find the first and third quartiles and then subtract them for the IQR.

Using Lightning Web Components for every interface seems like overkill. I'd recommend the user-centered design approach to really get to the root of the problem.

I think the key here is that the legacy billing system is being extended to add a SOAP endpoint. So I'd say Apex REST is the way to go, as it can directly consume the SOAP data.
