Question

Lorenzo is conducting a research study to understand the correlation between the incidence of breast cancer and the age among women. The women in the research study are from the same ethnic background and belong to the upper middle class. Lorenzo selects 30 women for the study and then divides them into three groups based on their age. The first group consists of women aged 25–35, the second group consists of women aged 36–50, and the third group consists of women aged 51–65. Which is likely to be a limitation in Lorenzo's method of research?

Answer 1

Answer: based on Lorenzo's methodology, his research is like to have a limitation for women aged 25-35.

Explanation: From research in many articles and different authors, conclusion has been made that breast cancer increases with age. Only 1 out of 1,500 female, aged 25-35 has breast cancer. And 1 out of 173 female, aged 36-50 has breast cancer. And as the age increase the number of breasts cancer case increases.

So if Lorenzo should use this methodology of age bracket. His research findings may not have any breast cancer case for women from 25-35 year. Which will limit his research findings to conclude that breast cancer are not seen in women aged 25-35.

Women aged 51-65 are more likely to have more number of breasts cancer case.
