To determine which grade is more likely to be members of the science club based on relative row frequency, we need to calculate the percentage of students in each grade who are members of the science club compared to the total number of students in that grade.
For Grade 7, the percentage of students who are members of the science club is:
(20/22) x 100% = 90.91%
For Grade 8, the percentage of students who are members of the science club is:
(20/28) x 100% = 71.43%
Therefore, based on the relative row frequency, Grade 7 students are more likely to be members of the science club compared to Grade 8 students.
The correct answer is: A. Grade 7
The following two-way table shows the data for the students of two different grades in a school:

Based on the relative row frequency, the students of which grade are more likely to be members of the science club? (5 points)
A: Grade 7
B: Grade 8
C: The students of both grades are equally likely to be members of the science club
D: No conclusion can be drawn about the chances of a student being a member of the science club
