The given differences between the test scores of Mrs. Li's students and the average test score of the school give us the order from lowest to highest marks of Mrs. Li's students as Cierra, Fionna, Bryan, Devaughn, Adam, and Elena. Hence, the 2nd option is the right choice.
What is average of data?
The average of data is the ratio of the sum of all observations in the data to the number of observations in the data. It can be written as:
[tex]\overline{x} = \frac{\sum x}{N}[/tex]
where [tex]\overline{x}[/tex] represents the average, x represents the observations, and N represents the number of observations.
How to solve the given question?
In the question, we are given the comparison of the test scores between Mrs. Li's students and the school's average test score.
The data is as follows: Adam +3 Bryan 0 Cierra –4 Devaughn +1 Elena +5 Fionna –2, where the shown figure is the difference between their respective score and the average test score of the school.
We are asked to identify the order from the given lists that show the students in order from lowest marks to highest marks.
A negative data means a score less than the average score.
Therefore, Cierra and Fionna got a score less than the average score, with Cierra scoring the least.
A data = 0 means a score equal to the average score.
Therefore, Bryan got a score equal to the average score.
A positive data means a score more than the average score.
Therefore, Adam, Devaughn, and Elena got a score more than the average score, with Elena getting the highest followed by Adam and the Devaughn.
Therefore the order looks like this: Cierra, Fionna, Bryan, Devaughn, Adam, and Elena, which is the 2nd option.
