Week3_Math_Graded_Q10: SSE calculation

[Anand Iyer]

Hi Team,

In the formula Pv=RT, 

 

if we consider P as the response variable (y-value), and T as the explanatory (x-value), you'll get SSE as 14.

if we consider T as the response variable, and P as the explanatory, SSE will not be 14.

As per physics, T should be considered the response variable, since it's plotted in the Y axis during lab experiments.

So, I believe the given option is not right.  

Else, please provide proper justification to this.  Also, tell us which variable should be treated as response and which one as explanatory, and why?

Hello, the equation describes temperature varying property of pressure. Because pressure is function of temperature. 

So, Temperature should be on x-axis as explanatory variable according to which pressure as a response variable changes.
Hope this helps.

@Anand, in Table it is clearly mentioned that  P is  the response variable.

Sherlock raised the issue in one thread.

[Anand Iyer]

yes, got it.

Thanks Malabika for following up and getting back to me on this.

My bad.
