Which of the following pairs of variables are likely to be negatively correlated

Video Transcript

So here we look at 1, simple choice: question right at the question asked which of the following pairs of venables? Is it like to have a negative correlation? I know a negative correlation means that so suppose you have 2 availables right. You look at less than negative correlation right suppose you have 2 valuables and even they have a negative coloration. That means when x, increase is nectar, decrease right when x decreases nectarine right, so that means they're a negative correlation. So, let's look at the choices, giving the question first says years of education salary. I think this is very like to correlate or so i think the first 1 is a positive combination. That means, when you have more years of education, is likely that you are going to get a better salary ran it's not nessereut on the fore. I think you get very likely pasipositive combination, not the negative, is not the correct answer. Second says the number of males run and the number of calories burned, and of course they are also this also in positive correlation right, as you 1 more and you bore more, carries right so as it passed through a combination and the third says, the square voltage Of a harem and its price and is also likely to be a positive correlation right, the bigger or halt price is like to be and finally of the force. Choice is a persons who hid in the favorite color and probably there's no correlation between these 2, the height in the collar part, with this new correlation, the corelation properties, lackly, 0 and finally, the speed of a car in the time to its destination. And this is bias negative correlation right because you you run faster and there usually the time takes get smaller. So the correct choice is the speed of a car and time it takes to the destination right itself. Speed of a car and time takes to destination and is lik, have a negative correlation.
