hello earning about positive negative correlation data statistics today first kind of correlation we are going to talk about today is a positive correlation and all this means is that thoughts are an established a scatter plot cuz they're all scattered around and not making an exact picture of the correlation just means that they're trying to make a picture that they're trying to be a line or some other s*** in this case they look like they're trying to be linear out we have strong and we have positive correlation the stronger the correlation the closer it is to make me laugh it still looks like it's made these are pretty close to making a line here we're going to say that this one has a straw correlation over here these are a little bit more spread out there still kind of aniline ask but they're not as tight and close together as the first one so we can consider this one a week positive correlation another word for correlation you might hear is Trend you've heard of things trending a lot a lot of times it can also mean that they're trending in a positive way or an egg release last thing I want to point out sometimes points are really close together, like right here, this is called Closter Skyway out here he doesn't really fit in a lot that is called out liar the next correlation is a negative correlation and again and said the work relations sometimes we see the word trend pop up just like pee positive Coral correlations and we have strong correlation and these are a little bit more spaced out so we're going to say that this one is to eat correlation are weak trend a lot tighter together definitely see they're more of a couple of them correlation just like in the positive correlation have a little cluster here I'm not really seeing it's nothing that stands out from the rest of the group The Last correlation is a no correlation and as you can see the points are trying to everywhere no one's really aniline whatsoever Tiny Tim the speaker like you guys at recess just kind of all over the parking lot and doing your own thing so when we see one like this we can't say the positive cancer always says it has a no correlation and the other word is Trend examples board problems to where they would be positive negative or no correlation think back to what we know about we know that is the slope of the line is positive we can have a positive over a positive or we can have a negative over and negative and they both are going to eat and if we have a positive over a negative integer rules correlation had a positive or negative relationship between them so looking at the problem take out the two things that are being compared and the time it takes to reach your destination are the two things being compared are the speed and the time it takes to reach your destination increasing or taking more or less time to reach your destination your speed is increasing it should take you less time to get to your destination I'm going 50 miles an hour and you're going 40 miles an hour my speeds faster time to get to where we're going so this is a negative correlation your shoe size there's the first thing we're comparing and the colors in a rainbow your shoe size it was what the colors in the rainbow are and vice a versa this one has no correlation and the last one the number of months in the amount in your savings account through to compare the number of months that are happening to the amount in your savings account increase like month 1 month to you account wow therefore this would be considered to have a positive correlation skip the next three and see if we can determine if they're positive negative or no correlation the number of books read the first thing we're comparing and the day of the week books on Monday or less on Tuesday if I read books on Wednesday at 6 on Sunday weather number 5 time running on a treadmill and the number of calories burned what time is my time increases on a check what should happen to the calories I'm burning and vice-versa positive correlation with this one number 6 the temperature on a warm day and the amount of snow on the ground temperature increases what's going to happen to the amount of snow on the ground correlation or trend negative or no correlation the number to go to the movies and the ticket sales are the two things that are being compared here well if the number of people who go to the movies increases what should happen to the ticket sales they should also increase we can also look at this in the reverse way that the number to the movies this has a positive correlation and I would expect test for the points to go up in a positive direction but all scattered around and braids the size of your TV and the time spent watching TV in a week experience it doesn't matter how big or small my TV is doesn't matter as much as I want so I believe this one has no correlation last but not least the amount of water you drink your drink and how thirsty you are I can be more or less thirsty thirsty positive amount of water drank over the decreasing my first would have a negative relationship in the opposite way if the amount of water you drink decreases what will happen to your first all should increase if you're not drinking why are you should be thirsty there for a negative
