Now we want to count the following information for each class: number of students with score above 90, number of failed students, and the average score after removing the highest and lowest scores, and then fill the results in the first row of each class (calculate in cell D1):

A
1 =E(‘A1:C19’).derive(:ScoreAbove90,:Failed,:AverageScore)
2 =A1.group(Class).run(~(1).ScoreAbove90=~.select(Score>=90).len(),~(1).Failed=~.select(Score<60).len(),~(1).AverageScore=~.sort(Score).m(2:-2).avg(Score))
3 return A1.new(ScoreAbove90,Failed,AverageScore)
