Understanding Scatter Graphs: Identifying Correlations and Making Predictions

The video tutorial explains the use of scatter graphs to identify relationships between data sets. It covers positive, negative, and no correlation, and how these can be visualized on a graph. The tutorial also discusses the use of scatter graphs for making predictions through interpolation and extrapolation, using a line of best fit.

Describe what is meant by negative correlation with an example.
