Questions and formulas:
Question: What is the largest number of Peak lessons taught when the Evaluation average (Before April 2009) was 4.4?
Formula: MAX(FILTER(G1, C1=4.4))
Formula2: MAX(FILTER(G2:G9, C2:C9=4.4))
Level: easy
Question: What is the mean Evaluation number (before April 2009) when the Peak lessons taught was less than 80 and the negative percentage of evaluations was 0.8%?
Formula: LET(query1,LET(query1,FILTER(A1:G1,D1="0.8%"),SUMMARIZE(CHOOSECOLS(query1,3),SUMX(CHOOSECOLS(query1,7)))),FILTER(query1,CHOOSECOLS(query1,2)<80))
Formula2: LET(query1,LET(query1,FILTER(A2:G9,D2:D9="0.8%"),SUMMARIZE(CHOOSECOLS(query1,3),SUMX(CHOOSECOLS(query1,7)))),FILTER(query1,CHOOSECOLS(query1,2)<80))
Level: hard
Question: What is the mean Evaluation number (Before April 2009) when the percentage of negative evaluations was 0.8% and the mean Evaluation number of April 2009 was 4.2?
Formula: UNIQUE(CHOOSECOLS(FILTER(A1:G1,(D1="0.8%")*(B1=4.2)),3))
Formula2: UNIQUE(CHOOSECOLS(FILTER(A2:G9,(D2:D9="0.8%")*(B2:B9=4.2)),3))
