We investigated the weight of food wasted per day in Hot Lunch because we wanted to show people how much precious food, which people in poor countries need so badly, is wasted by the middle school students. To do this we weighed the buckets of wasted food every day for one week.
To work out the mean, we added the weights of food wasted each day together and divided them by five: 6,282g + 2,932g + 6,142g + 4,732g + 6,142g = 26,230g : 5 = 5,246g
To work out the median, we ordered the weights lowest to highest and took the one in the middle: 2,932g, 4,732g, 6,142g, 6,142g, 6,282g. Middle = 6,142g.
To work out the range, we subtracted the lowest weight from the highest: 6,282g - 2932g = 3,350g
To work out the weight of wasted food, we measured the buckets in the lunchroom without food (306g). Then we measured the buckets with food every day after Hot Lunch, added their weights together and subtracted the weight of the buckets (918 as there are three buckets). Ex. 1,600g + 1,560g + 3,900g = 7,060g - 918g = 6,142g
We are using this data to show people how much food we are wasting.
To make this even more clear to people we found out how many plates of food could be made of the food we waste.
We came out with this: The average food only the middle school hot lunch students waste every week could fill 50 plates. That could give 50 children in poor countries a meal.
