Question

a student looking at their data and found out that one of their force measurements was not consistent with the previous measurement. what could be the reason? the student was controlling how much mass was in the cart. the student did not complete enough trials. the student was releasing the cart at the same position. the student did not control the variable of zeroing the spring scale before measuring. if a double bar graph compares the number of students who prefer dogs versus cats in different grades, what would the x - axis most likely show? the different grades (e.g., grade 6, grade 7, grade 8) the type of pet (dogs or cats) the number of students the total number of pets

Explanation:

For the first question, not zeroing the spring - scale can lead to inconsistent force measurements. For the second question, in a double - bar graph comparing students' pet preferences across grades, the x - axis typically shows the independent variable which is the different grades.

Answer:

1. The student did not control the variable of zeroing the spring scale before measuring.
2. The different grades (e.g., Grade 6, Grade 7, Grade 8)
