Thanks for the great video! Also, I think it's the first time I'm hearing a New-Zealander accent. So sweet!

Awesome explanation. Loved your comment on Sampling error that it's not an error per se but the variation due to different samples :)

just have 1 question while considering the Age co-effcient we considersed it as for every 1 year the car gets older and when it cames to km co-efficient you considered for every 1000 km, just had a small doubt: why didnt we go with every 1km instead of every 1000km, the car travels more its price gets reduced by a certain range value, since for Age we consider as for every 1 year . may i know on what after the unit 1 or 1000 gets decided for interpreation ?

What do you mean interval regression.thank you

if you want to estimate the price within some confidence interval, how can you come up with the standard error for the price?

Hi! thank you! therefore, the CI should always contain our size effects/coefficients, right?
