This case study examines the relationship between breakfast eating habits and obesity in school kids from low-income families. Researchers compared body mass indices (BMIs) of 625 children to the number of times - out of 9 days - the children reported eating cereal for breakfast. Kids who reported eating breakfast 4 out of 9 days tended to be in the 95th percentile for BMIs, indicating obesity. Kids who reported eating cereal 9 out of 9 days tended to be in the 65th percentile, indicating healthy weights. The study was funded in part by a regional dairy council. Which of the following describes a possible difficulty with this study?
a. Hawthorne effect
b. Confounding variables
c. Ecological validity
d. All of the above
