Can you draw a trend line? If so, which direction does it point as you move from left to right on the graph?
Type of Correlation: Strong positive. Scatter Plot:
Practice makes perfect
When analyzing data using a scatter plot, there are three general outcomes for the correlation of the data: positive correlation, negative correlation, or no correlation.
Observation
Type of Correlation
As x increases, y increases.
Positive
As x increases, y decreases.
Negative
There is no visible pattern.
No
We can graph the given data as a scatter plot. Are there any trends?
It looks like there is some kind of correlation. Let's draw a line of fit, or trend line, to help us identify the type of correlation. To do so, we will draw a line that appears to fit the data closely.
As x-values increase, y-values also increase. This indicates a positive correlation between x and y. We can see that the line fits the points very well, so we can even say that the correlation is strong positive.
