Eleanor Rigby's research is about, whether 'topical or oral flea preventative measures are more effective for treating fleas in dogs'
Sampling is the technique of selecting study units for conducting the research. She draws a sample of total 60 dogs suitable for her study.
Stratified sampling means sample arrangement in a structure of subgroups called 'stratas'. The stratas are similar within themselves & differ from each other. She divides sample dogs into three stratas based on their size & weight. And; similar weight & size dogs are arranged in their corresponding 'small', 'medium' or 'large' sized dogs strata. So, the dogs stratas are similar within themselves & differ from each other, in regards to their weight & size. Hence, she has used Stratified Design
