A science class breaks into four groups and tests the pH of the soil surrounding the school. Each group goes to an area that is three meters squared (3m 2) in size and tests the soil four different times within that square. The data collected is then placed into a table for everyone to see as shown below. Four students draw the following conclusions from the data:
Student 1: Group D’s data should be discarded because it is not similar enough to the other groups' data.
Student 2: There must be something near the parking lot that causes the pH of the soil to be higher and the class should design a new experiment to determine what it may be.
Student 3: There are definitely more magnesium ions in the soil near the parking lot, and that is why the pH of the soil is higher there.
Student 4: The pH of the soil in the ball field should be measured again because no two readings were identical.

Which student’s conclusion is scientifically valid based on the data in the table above?

A. Student 1

B. Student 2

C. Student 3

D. Student 4
