This is my Statistical Investigation on Room 1's Favourite chocolate bars. I had to survey 21 students on their favourite chocolate bars.

Milky Ways were the favourite chocolate bars in Room 1.

Thirteen students liked Milky Way chocolate bars.

Perky Nanas were the least favourite bars. Zero people chose Perky Nanas.

Milky Bars, Crunchie Bars and Peanut slabs were not very popular.
