    Exercise \(\PageIndex{1}\)

    Does the scatter plot appear linear? Strong or weak? Positive or negative?

    This is a scatterplot with several points plotted in the first quadrant. The points form a clear pattern, moving upward to the right. The points do not line up , but the overall pattern can be modeled with a line.
    Figure \(\PageIndex{4}\)

    Answer

    The data appear to be linear with a strong, positive correlation.

    Exercise \(\PageIndex{3}\)

    Does the scatter plot appear linear? Strong or weak? Positive or negative?

    This is a scatterplot with several points plotted in the first quadrant. The points move downward to the right. The overall pattern can be modeled with a line, but the points are widely scattered.
    Figure \(\PageIndex{5}\)

    Exercise \(\PageIndex{4}\)

    Does the scatter plot appear linear? Strong or weak? Positive or negative?

    This is a scatter plot with several points plotted all over the first quadrant. There is no pattern.
    Figure \(\PageIndex{6}\)

    Answer

    The data appear to have no correlation.
