To draw a graph of the relationship between the quantity of ice cream consumed and the price of ice cream, we need to hold the temperature constant at any of the four levels shown in the table. This is because we want to isolate the effect of the price of ice cream on the quantity consumed, and holding the temperature constant allows us to do that. If we were to increase or decrease the temperature as the price rises, we would introduce a confounding variable that would make it difficult to draw meaningful conclusions about the relationship between price and quantity consumed. Similarly, picking a specific temperature that prevailed when the price was $2.00 or holding the price constant at any of the five levels shown would not allow us to isolate the effect of price on quantity consumed.
