The scatterplot shows a few patterns of clustering and one outlier.
There is a tightly packed cluster of data plots between 30 to 37 degrees Fahrenheit on the horizontal axis and 42 to 48 cups of coffee sold on the vertical axis. This suggests that there is a positive correlation between temperature and the number of cups of coffee sold within this range.
There is also a loosely packed cluster of data plots between 40 to 51 degrees Fahrenheit on the horizontal axis and 30 to 38 cups of coffee sold on the vertical axis. This indicates that there may be a weaker positive correlation between temperature and coffee sales within this range.
There is an outlier at 62 degrees Fahrenheit and 5 cups of coffee sold. This data point is far away from the clusters and may need to be further investigated to understand why it deviates significantly from the general trend.
Use the image to answer the question.
A scatterplot shows the number of cups of coffee sold versus temperature.
The horizontal axis shows temperature, in degrees Fahrenheit, ranging from 0 to 70 in increments of 5, with an initial jump from 0 to 25. The vertical axis shows number of cups of coffee sold, ranging from 0 to 60 in increments of 10. A kink is shown on the horizontal axis close to origin. A tightly packed cluster of data plots is plotted between 30 to 37 on the horizontal axis and 42 to 48 on the vertical axis. A loosely packed cluster of data plots is plotted between 40 to 51 on the horizontal axis 30 and 38 on the vertical axis and. A dot is plotted at 62 on the horizontal axis and 5 on the vertical axis.
