Final answer:
The primary task when analyzing a scatterplot to linearize the data is to identify a relationship between the variables.
Step-by-step explanation:
When analyzing a scatterplot to linearize the data, the primary task is to identify a relationship between the variables. This can be done by examining the scatterplot for a clear pattern or trend.
If the data points form a straight line or exhibit a linear pattern, then the variables would be good candidates for linear regression. In this case, you can use techniques like calculating the least-squares line or finding the correlation coefficient to further analyze and linearize the data.
