Conclusion

My hypothesis is both correct and incorrect for my investigation. I predicted that Café A would be the dirtiest, but in actual fact, it was Café C. I also predicted that Café B would be the cleanest and I was correct for that prediction. I discovered that the one of the most popular, but smallest cafés was the dirtiest. The result of mould grown is very useful to cafes, because their employees are not doing enough to keep their cafes as clean and hygienic as possible.  I learnt that an ‘A’ Hygiene Grading does not necessarily mean that the café is flawless. The cleanest café was Café B.
