Data Set A:

A student conducted an experiment to determine if the temperature of the water affected the breathing rate of the freshwater sunfish. Temperature was measured in degrees Celsius and breathing rate was per minute. The data collected was as follows:

1. At what temperature was the breathing rate the highest?

Data Set B:

A student wanted to test to see how temperature affected plant growth. He used the same type of plant, planter, amount of water, and fertilizer. The plants were left in controlled temperature chambers for 15 days, and at the end of 40 days, the height of the plants was measured in centimeters. The data collected was as follows:

Data Set C:

A siamang gibbon is an ape that lives in the rain forest of Southeast Asia. These gibbons depend on more than 160 species of rain forest trees and other plants for food. Half of the siamang gibbon’s diet comes from leaves. Forty percent of its diet comes from fruits, and the remaining portion of its diet comes from flowers, buds, and insects. Many acres of rain forest are being cleared for palm-oil and coffee plantations.
