Hello,
today's salary assignment. I have some doubt in assignment
1. In first question they ask about increment in total salary count from 2011 to 2014, so how to find that exact increment number... using graph we can show that peak...but they ask about how much increment???

2.In second question we have to find top earning emp. from each year?? or an employee who was employee from 2011-2014 and earning top salary??

Hi Sir

I wanted to bring something from the self-learning vieods of ML course to your notice , which I found a little probamatic. i am attaching a screenshot of the polynomial regession equassion, and there is an equation x2' =X22 . Now after taking your session and going through the ebooks, i understoood that its actually X2^2 . But before that it was very confusing for me to actually understand what it is. I have gone through videos onf many courses and there are multiple cases where such confing mistakes are there. I am not sure how to bring thsi to the notice of Simplilearn team, but it would have been better if they could rectify these things.

Sir , I havea question regarding the Ad sales data multiple regression.
The coefficients for TV, Radio,Newspaer was respectively .046,.21 and .069. Does that mean that Radaio ad is more significant in predicting sales?

If that is the case, then shouldnt correation between sales-Radio be more than that of Sales-TV?
But from the corr tablle we see Sale-TV corr is .78, whereas Sales-Radio corr is .57.
Why is it so?

Attaching the screenshot for your reference.

could you please check the exercise?
I have a Q about the removing of outlier from the two side
I tried to use the follwoing code:

filter = [x for x in data['RM'].values if x > 5 and x < 7.6]
RM_data_rem = data[filter]
sns.boxplot(RM_data_rem['RM'])

but I received the following error:
""None of [Float64Index([6.575, 6.421, 7.185, 6.998, 7.147, 6.43, 6.012, 6.172, 5.631,\n 6.004,\n ...\n 5.39, 5.794, 6.019, 5.569, 6.027, 6.593, 6.12, 6.976, 6.794,\n 6.03],\n dtype='float64', length=464)] are in the [columns]"
