Scatter graphs and correlation
{"Image DocumentName": "Scatter graphs and correlation", "Image ImageDescription": "When one variable decreases as the other variable increases, we have a negative correlation. Rainfall (mm) Temperature(\u00b0C) For example, this scatter graph shows that there is a strong negative correlation between rainfall and hours of sunshine. Establish that this graph shows that the more rain there is, the colder it is. In other words, the lower the temperature the greater the rainfall. The points lie close to a downward sloping line of best fit.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
