Estimating the line of best fit exercise

Video transcript

find the line of best fit or mark that there is no linear correlation so let's see we have a bunch of data points now we want to find a line that at least shows the trend in the data and this one seems a little difficult because if we ignore these three points down here maybe we could do a line that looks something like this it seems like it kind of approximates this trend although this doesn't seem like a great trend and if we ignore these two points right over here we could do something like maybe something like that but we can't just ignore points like that so I would say that there's actually no good line the best fit here so let me check my answer let's try a couple more of these find the line of best well this is this feels very similar to feely feels like there's no I mean I could do that but I'm ignoring these two points I could do something like that then I'd be ignoring these points so I'd also say no good best fit line exists so let's try one more so here it looks like there's very clearly this trend and I could try to fit it a little bit better than its fit right now so it feels like something like that fits this trendline quite quite well I could maybe drop this down a little bit something like that let's check my answer a good best find a good best fit line exists let me check my answer and got it right
