Celeste's study on the relationship between weight and popularity is questionable. Celeste could be assuming the connection between being overweight and popularity. Although she found a strong correlation (0.92) between the variables, this does not guarantee a connection. According to the textbook, Research Methods for the Behavior Sciences, samples generally exhibit similarities to their populations, researchers want more trust in ensuring that the samples they use are accurate examples of the population they are examining (Gravetter, 2018). The information presented on demographics, samples, and sampling procedures provides insight into the potential limits of Celeste's research. According to the lecture, Celeste's study seems to use a convenience sample, which is a type of sampling that does not involve probability (Tarner). This applies because Celeste selected students from a local school because of the convenience. Although, convenience sampling is commonly used in research, it might result in biased samples that may not accurately reflect the broader population. This means that they used the accessible population (Gravetter, 2018). Therefore, she may be drawing false conclusions and may be assuming a relationship between being overweight and being popular based on a flawed participant selection and process
