A scatterplot shows the number of cups of coffee sold versus temperature.

Question

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.Numbers of Cups of Coffee Sold Versus TemperatureInterpret the scatterplot by describing any outliers and patterns of clustering.

Answer 1

The kink shown on the horizontal axis close to the origin may indicate a sudden change in temperature that affected the number of cups of coffee sold. The tightly packed cluster of data points between 30 to 37 on the horizontal axis and 42 to 48 on the vertical axis suggests that there is a positive correlation between temperature in this range and the number of cups of coffee sold. This means that as the temperature increases within this range, more cups of coffee are sold.

The loosely packed cluster of data points between 40 to 51 on the horizontal axis and 30 and 38 on the vertical axis suggests that there may be more variability in the number of cups of coffee sold at higher temperatures within this range. This could be due to other factors such as day of the week, time of day, or promotions affecting sales.

The dot plotted at 62 on the horizontal axis and 5 on the vertical axis is an outlier, as it is far away from the clusters of data points. This suggests that at a temperature of 62 degrees Fahrenheit, only 5 cups of coffee were sold, which is significantly lower compared to the other data points. This outlier could indicate a potential anomaly or unusual circumstance affecting sales at that specific temperature.
