Question

Jake concluded that the runoff had little effect on the dissolved oxygen levels, and Aisha concluded that the runoff had a major effect on dissolved oxygen levels. What is the most likely reason that Jake and Aisha formed different conclusions? Each person used different references for comparison. Jake recorded the wrong measurements on two days. Aisha converted the units before creating her graph. The students used different ranges for their y axes.

Answer 1

The best answer is Option D. The students used different ranges for their y-axes.

Step-by-step explanation:

The only possible reason is the difference of the ranges on y-axes due to both of the students get different results. But both of them are right according to the ranges they have taken for conclusion making graph.

Answer 2

The correct answer is option The students used different ranges for their y axes.

The range of the Y axis shows the variation in the experimental condition. The range on each axis should be chosen in such a way that the data is reflected properly. The changes in the portion of the Y axis can change the conclusion dramatically.

In this case, Jake must have chosen a range, which is very large, so, the changes in smaller quantity does not result in significant impact on the graph. In case of Aisha, the range must be very small, due to which a smaller change in the range create a major impact on the graph.
