I think it's individual value but again I could be mistaken. I haven't covered this service in a really long time. You can check that out. Yeah, I see it. If you compare it to the average value, it seems like it is accurate. But if you see the individual values, they are way off. By a factor of 3% in the first one and then 2.5% on the second one. So yeah, by way off, I'm saying compared to C. So yeah, I don't think from that, from looking at this, it should not be the average. Because average could tell you a weird story.

डो लोग 1.95, 1.93 हैं। आप एक पिर्संटेज नहीं करते हो जाएं. स्टुडेट B में दो लोग बहुत बखें हैं। वे प्रोटर में आपका स्टुटेट जाएं। और वे एक बाद अपर बखें हैं। वे प्रोटर में आपका स्टुटेट जाएं।

it is individual result vs true value is what i see the difference squared gives you std deviation ka concept (which is a more relevant idea you will learn in stats)
