hey can you tell me how to revise properly for the exam. i know there is a lot of content to cover. ive made notes, yes, but even that ia long🙄

@@debarshiroy2939 for english go through the relevant parts from better english book. for maths and stats revise the same questions for which you have video solutions available, no need to practice extra questions. just revise the ones already done in revision videos, live interaction videos, solve with me videos and so on. just make sure you cover all the video materials provided by the IIT. don't skip any. and CT is logic and reasoning based no mugging required there so thats on you.

@@efficaciousuave CT is pure logic. but the prblm is with maths. it is the hardest of all 4.the assignment ques are really tough. so if that kind of ques come again in the exam, i dunno what to do😶

I would like to voice a concern. She says that y will be the two values of 0 and 1 and x will be the numerical values. But isn't it supposed to be the reverse. The x axis would reflect the two dichotomous values and the y axis would reflect the numerical values. Agreed it doesn't effect the point bi serial correlation, but still.

It does effect "the formula doesn't makes sense if "x represents marks",. I was thinking the same thing ~ scratching my head

@ZAKIY-kg4zl 10 ай бұрын

The X denotes the numerical variables and Y denotes the gender to compute Y0 and Y1. It is not specifically saying X-axis and Y-axis @@lack5859

@@lack5859 yes i think the graphical representation messed us up, she should have used x axis for numerical and y for categorical. We should not be thinking of best line fit and positive negative slopes when dealing with point biserial correlation, they have different domains
