Devante wondered if there was a correlation between math scores and science scores on the cumulative tests, so he collected data based on a semester exam score for math and science. The data is shown in the scatterplot. Based on this data, which inference is valid?

Since the data points on the scatterplot appear to form a relatively straight line sloping upwards from left to right, a valid inference would be that there is a positive correlation between math scores and science scores. This means that as math scores increase, science scores also tend to increase, and vice versa.
