10/3/14

This weekend's homework is to continue working on your data analysis. It is suggested that you complete a draft of the thorough analysis of your (at least) 3 chosen survey questions for Monday.

Sample Survey Question: What does “healthy eating” mean to you?

Sample Responses

·       Fruits, vegetables, organic, local, not eating too much à no overeating

·       Nutritious food

·       Eating things that are good for one’s body

·       Stuff that tastes bad but good for you

·       Eating properly as to what I should put in my body and balancing what I need

·       Controlled portions, balanced meals

·       Having a balanced diet w/ vegetables and proteins and the occasional “treat”

·       A good balanced diet

·       Salad, no fast food restaurants, food that is natural

·       Eating things that are good for you, good for your body

Sample Inferences

Good/nutritious food – 5/10 responses

Balance/not overeating – 5/10 responses

Fruits and vegetables – 3/10 responses

Avoiding certain foods – 2/10 responses

Sample Conclusions

Seniors enrolled in Food Science class at School of the Future seem to view healthy eating as involving the quality, amount of food consumed, and types of food consumed. Half of responses analyzed mentioned that food should be “nutritious” or “good” (and good in this case is being interpreted as nutritious). Another common aspect of healthy eating among students was the idea of balance. Again, half of responses stated the words “balance,” “control” or another term that connotes an effort to not overeat. At the same time, it was unclear whether “balance” referred to the amount of food eaten or the variety of foods eaten. Only 30% of respondents mentioned that healthy eating involves eating a certain types of food such as fruits and vegetables. Another 20% of students did report that healthy eating involves avoiding or minimizing certain foods like “fast food” or “treats.” Taken together, this shows that 50% of subjects viewed healthy eating as involving choosing to eat certain foods and/or avoiding eating others.

10/2/14

Tonight's homework is to continue organizing and thoroughly analyzing your data from three survey questions. This entails graphing, making inferences, connecting the data to your EQ and hypothesis. A draft of the analysis for one question is due in class tomorrow.
