Je maakte een correcte berekening en je paste de factoren 1 en 2 correct aan. Verder gebruikte je de correcte test: de Chi-kwadraat test. Je opteert voor deze test omdat je werkt met de Hi/Lo variabelen.  
 
Je vormt ook een correcte conclusi. Er bestaat inderdaad een verband tussen beide variabelen. Echter, om je conclusie te vormen, kijk je enkel naar de p-waarde en naar het feit of deze groter of kleiner is dan de door jouw opgestelde type 2 fout. Aan je conclusie had je het volgende nog kunnen toevoegen: Als je naar de grafiek kijkt, merk je op dat de blokken allemaal een grijze kleur hebben. Dit wijst erop dat de cellen onderling, geen significante verschillen vertonen. Daarna bekijk je de hoofddiagonaal (van linksboven naar rechtsonder). Daar zien we dat de blokken allemaal naar beneden wijzen. Dit zegt dat de reële frequentie lager is dan de verwachte frequentie (stippellijn). Dan kijken we naar de andere diagonaal (van linksonder naar rechtsboven). Hier zie je dat de blokken allemaal boven de stippellijn liggen wat er dus op wijst dat de reële frequentie hoger ligt dan de verwachte frequentie. Deze twee diagonalen spreken elkaar tegen en dus kunnen we stellen dat er een verband bestaat. Omdat de hoofddiagonaal negatief is (alle blokken wijzen naar beneden). Spreken we van een negatief verband.  
 
Je had ook een verfijnde oplossing kunnen maken. Je doet dit door de data in te geven met A en B’s uit de Excel. In plaats van een gewone Chi-squared-test te gebruiken, gebruik je de “Exact Pearson Chi-squared by simulation”. Je interpreteert die op de zelfde wijze als de grove oplossing. Hieronder kan je een correcte berekening terugvinden van een verfijnde oplossing: http://www.freestatistics.org/blog/index.php?v=date/2010/Nov/18/t1290083384wud1i77335tog0r.htm/.
